Which relationship is illustrated by a tapeworm living in the intestine of a human?
- A.
Commensalism
- B.
Predator--prey
- C.
Mutualisms
- D.
Parasitism
Correct Answer
D. ParasitismExplanation
A tapeworm living in the intestine of a human illustrates parasitism. In parasitism, one organism benefits (the tapeworm) while the other is harmed (the human). The tapeworm feeds off the nutrients in the human's intestines, causing harm and potentially leading to health issues for the human host. This relationship is a classic example of parasitism, where one organism lives at the expense of another.Rate this question:

A fungus is an example of:
- A.
An herbivore
- B.
A saprophyte
- C.
An autotroph
- D.
An omnivore
Correct Answer
C. An autotrophExplanation
A fungus is an example of an autotroph because it is capable of producing its own food through the process of photosynthesis. Unlike herbivores and omnivores that rely on consuming other organisms for nutrition, and saprophytes that obtain nutrients from decaying organic matter, fungi have the ability to convert sunlight into energy and synthesize organic compounds. This makes them self-sufficient and independent in terms of their nutritional requirements, classifying them as autotrophs.Rate this question:

One biotic factors that limits the carrying capacity of any habitat is
- A.
The availability of water
- B.
Level of atmospheric oxygen
- C.
Activity of decomposers
- D.
Amount of soil erosion
Correct Answer
C. Activity of decomposersExplanation
The activity of decomposers is a biotic factor that limits the carrying capacity of any habitat. Decomposers play a crucial role in breaking down organic matter and recycling nutrients back into the ecosystem. If the activity of decomposers is low, the rate of nutrient recycling decreases, leading to a decrease in overall productivity and the ability of the habitat to support a large population. Therefore, the activity of decomposers directly affects the carrying capacity of the habitat.Rate this question:

Which is an abiotic factor that would affect the ability of a species of tree to survive in a particular habitat?
- A.
Availability of minerals in the soil
- B.
Type and number of tree parasites
- C.
Climax vegetation of the area
- D.
Type and number of herbivores present
Correct Answer
A. Availability of minerals in the soilExplanation
The availability of minerals in the soil is an abiotic factor that can affect the ability of a species of tree to survive in a particular habitat. Trees require certain minerals, such as nitrogen, phosphorus, and potassium, for their growth and development. If these minerals are lacking in the soil, it can limit the tree's ability to obtain the necessary nutrients for survival. Conversely, if the soil has an abundance of minerals, it can provide favorable conditions for the tree's growth and increase its chances of survival in the habitat.Rate this question:

For a producer to maintain itself, which factor must be present in its environment?
- A.
Carnivores
- B.
Herbivores
- C.
Sunlight
- D.
Parasites
Correct Answer
C. SunlightExplanation
Sunlight is necessary for producers to maintain themselves because they undergo photosynthesis, a process by which they convert sunlight into energy. This energy is then used to produce food and nutrients for themselves and other organisms in the ecosystem. Without sunlight, producers would not be able to carry out photosynthesis and would eventually die, disrupting the entire food chain. Carnivores, herbivores, and parasites are all part of the ecosystem, but sunlight is the essential factor for the survival and growth of producers.Rate this question:

The removal of nearly all the predators from an ecosystem would most likely result in
- A.
An increase in the number of carnivore species
- B.
A decrease in new predators migrating into the ecosystem
- C.
A decrease in the size of decomposers
- D.
An increase in the number of herbivores
Correct Answer
D. An increase in the number of herbivoresExplanation
The removal of predators from an ecosystem would lead to a decrease in predation pressure on herbivores. With fewer predators to keep their populations in check, herbivores would have less competition for resources and would be able to reproduce and thrive. This would result in an increase in the number of herbivores in the ecosystem.Rate this question:

Many years ago, a volcanic eruption killed many plants and animals on an island. Today the island looks much as it did before the eruption. Which statement is the best possibly explanation for this?
- A.
Altered ecosystems regain stability through the evolution of new plant species
- B.
Destroyed environments can recover as a result of the process of ecological succession
- C.
Geographic barriers prevent the migration of animals to island habitats
- D.
Destroyed ecosystems always return to their original state
Correct Answer
B. Destroyed environments can recover as a result of the process of ecological successionExplanation
Destroyed environments can recover as a result of the process of ecological succession. Ecological succession is the process by which an ecosystem gradually recovers and regains stability after a disturbance, such as a volcanic eruption. Over time, new plant species colonize the area, leading to the establishment of a new community. This process allows the ecosystem to rebuild and eventually resemble its pre-disturbance state. It is important to note that the recovery may not be identical to the original state, as altered ecosystems can regain stability through the evolution of new plant species.Rate this question:

Organisms that eat cows obtain less energy from the cows than the cows obtain from the plants they eat because of the cows.
- A.
Pass on most of the energy to their offspring
- B.
Convert solar energy to food
- C.
Store all their energy in milk
- D.
Use energy for their own metabolism
Correct Answer
D. Use energy for their own metabolismExplanation
Organisms that eat cows obtain less energy from the cows than the cows obtain from the plants they eat because the organisms use energy for their own metabolism. When cows consume plants, they convert the solar energy from the plants into food through the process of photosynthesis. However, when organisms consume cows, they need to use some of the energy obtained from the cows to fuel their own metabolism and bodily functions. As a result, there is less energy available for the organisms that eat cows compared to the energy obtained by the cows from the plants they consume.Rate this question:

Two closely related species of birds live in the same tree. Species A feeds on ants and termites, while Species B feeds on caterpillars. The two species coexist successfully because
- A.
Each occupies a different niche
- B.
They interbreed
- C.
They use different methods of reproduction
- D.
They live in different habitats
Correct Answer
A. Each occupies a different nicheExplanation
The two closely related species of birds coexist successfully because each occupies a different niche. This means that they have different ecological roles and utilize different resources within their shared environment. Species A feeds on ants and termites, while Species B feeds on caterpillars. By occupying different niches, they are able to avoid direct competition for food and other resources, allowing both species to thrive in the same tree.Rate this question:

What impact do the amounts of available energy, water, and oxygen have on an ecosystem?
- A.
They act as limiting factors
- B.
They are used as nutrients
- C.
They recycle the residue of dead organisms
- D.
They control the environmental temperature
Correct Answer
A. They act as limiting factorsExplanation
The amounts of available energy, water, and oxygen in an ecosystem act as limiting factors. This means that the availability of these resources can limit the growth, reproduction, and survival of organisms within the ecosystem. For example, if there is a limited amount of water available, it can restrict the growth of plants and limit the availability of water for other organisms. Similarly, a lack of oxygen can limit the survival of aquatic organisms. Overall, the limited availability of energy, water, and oxygen can have a significant impact on the overall functioning and dynamics of an ecosystem.Rate this question:

Which human activity will most likely have a negative impact on global stability?
- A.
Decreasing water pollution levels
- B.
Increasing recycling programs
- C.
Decreasing habitat destruction
- D.
Increasing world population growth
Correct Answer
D. Increasing world population growthExplanation
Increasing world population growth is likely to have a negative impact on global stability because it puts additional strain on resources such as food, water, and energy. As the population grows, the demand for these resources increases, leading to potential shortages and environmental degradation. This can result in conflicts over resources, increased pollution, and habitat destruction as more land is needed for housing and agriculture. Therefore, increasing world population growth can have detrimental effects on global stability.Rate this question:
