1.

Which of the following relationships would be considered a parasitic relationship?
- A.
  
  Clown Fish and Sea Anemone
- B.
  
  Guinea Worm and Human
- C.
  
  Honey Bee and Flower
- D.
  
  Egret and Cow
Correct Answer
B. Guinea Worm and Human

Explanation
A parasitic relationship is one in which one organism benefits at the expense of the other. In the case of the Guinea Worm and Human, the Guinea Worm is a parasite that lives inside the human body and causes painful infections. The Guinea Worm benefits from the human host, while the human suffers from the infection. This relationship fits the definition of a parasitic relationship.

What would happen to the Plankton population if the Salmon and Lake Trout were to leave?
- A.
  
  All populations would go up.
- B.
  
  All Populations would go down.
- C.
  
  The Plankton population would go down and the forage fish would go up.
- D.
  
  The Plankton population would go up and the forage fish would go down.
Correct Answer
C. The Plankton population would go down and the forage fish would go up.

Explanation
If the Salmon and Lake Trout were to leave, the Plankton population would go down. This is because Salmon and Lake Trout feed on Plankton, so their absence would result in a decrease in the Plankton population. On the other hand, the absence of these predators would lead to an increase in the forage fish population, as they would no longer be preyed upon by the Salmon and Lake Trout.

The ability of a given area to continually supply adequate food, water, and shelter for the organisms that live in an ecosystem is know as:
- A.
  
  Community
- B.
  
  Abiotic Factors
- C.
  
  Carrying Capacity
- D.
  
  Ecology
Correct Answer
A. Community

Explanation
The correct answer is Carrying Capacity. Carrying capacity refers to the maximum number of individuals of a species that an ecosystem can support sustainably. It takes into account the availability of food, water, and shelter, and ensures that these resources are not depleted to the point where the ecosystem becomes unable to support the organisms living in it.

Zebra Mussels reproduce and spread quickly, reducing food resources and crowding native species. This results in
- A.
  
  A decrease in native producer populations.
- B.
  
  A increase in native producer populations.
- C.
  
  Mutually beneficial relationships with native species.
- D.
  
  Higher reproductive rates for native species.
Correct Answer
A. A decrease in native producer populations.

Explanation
Zebra mussels reproduce and spread quickly, which leads to a decrease in native producer populations. This is because zebra mussels compete with native species for resources, such as food and space, and can outcompete them due to their rapid reproduction and spread. As a result, the native producer populations are reduced, as they have less access to the necessary resources for growth and survival.

Check off all of the invasive species found in NJ
- A.
  
  Black Locust
- B.
  
  Black Swallow-worts
- C.
  
  Water Chestnut
- D.
  
  Common Reed
Correct Answer(s)
A. Black Locust
B. Black Swallow-worts
C. Water Chestnut
D. Common Reed

Explanation
The correct answer includes Black Locust, Black Swallow-worts, Water Chestnut, and Common Reed. These are invasive species found in New Jersey. Invasive species are non-native species that can cause harm to the environment, economy, or human health. They often outcompete native species for resources and disrupt the natural balance of ecosystems. It is important to identify and manage invasive species to protect native biodiversity and maintain ecosystem health.

Which of the following statements is not a reason to be concerned about invasive species?
- A.
  
  They cost tax payers millions of dollars each year.
- B.
  
  They are a huge culprit behind many of our endangered species being endangered.
- C.
  
  They create better fishing experience by catching bigger fish.
- D.
  
  They are a nuisance to control.
Correct Answer
C. They create better fishing experience by catching bigger fish.

Explanation
The statement "They create better fishing experience by catching bigger fish" is not a reason to be concerned about invasive species because it suggests a positive outcome. Invasive species can have negative impacts on ecosystems, such as outcompeting native species for resources, disrupting food chains, and causing ecological imbalances. While they may increase fish populations temporarily, this can lead to long-term negative consequences for the overall health and diversity of the ecosystem. Therefore, the statement is not a valid concern regarding invasive species.

According to the following video, what seems to have the biggest impact on the piping plover population?
- A.
  
  Predators
- B.
  
  A Low Population
- C.
  
  Water
- D.
  
  Humans and Pets
Correct Answer
D. Humans and Pets

Explanation
The video suggests that humans and pets have the biggest impact on the piping plover population. This could be due to factors such as habitat destruction, disturbance of nesting sites, and predation by domestic animals. Human activities and the presence of pets can disrupt the natural environment of the piping plovers, leading to a decline in their population.

An organism that eats both plants and meat is described as a:
- A.
  
  Herbivore
- B.
  
  Producer
- C.
  
  Carnivore
- D.
  
  Omnivore
Correct Answer
D. Omnivore

Explanation
An organism that eats both plants and meat is described as an omnivore. This means that it has a varied diet and can consume both plant-based foods and animal-based foods. Unlike herbivores that only eat plants or carnivores that only eat meat, omnivores have the ability to adapt to different food sources and obtain nutrients from both plant and animal sources. This allows them to have a more diverse and flexible diet compared to other types of organisms.

The study on the way organisms interact with their environment is called:
- A.
  
  Ecology
- B.
  
  Zoology
- C.
  
  Geology
- D.
  
  Biology
Correct Answer
A. Ecology

Explanation
Ecology is the study of how organisms interact with their environment. It focuses on understanding the relationships between organisms and their surroundings, including other organisms, the physical environment, and the resources available. This field of study helps scientists understand how ecosystems function and how human activities can impact the natural world.

The arrows point in the direction of...
- A.
  
  They point in the direction of what eats what.
- B.
  
  They point in the direction of the flow of energy.
- C.
  
  They point in no particular direction.
Correct Answer
B. They point in the direction of the flow of energy.

Explanation
The arrows in the diagram indicate the direction of the flow of energy. This means that they show the transfer of energy from one organism to another in a food chain or food web. The arrows point from the organism being eaten to the organism doing the eating, representing the flow of energy as it is transferred from one level of the food chain to another.

Where would you most likely find this animal in a dune ecosystem?
- A.
  
  The Beach Zone
- B.
  
  The Trough/Interdunal Pond
- C.
  
  Foredune
Correct Answer
C. Foredune

Explanation
In a dune ecosystem, the animal would most likely be found in the foredune. The foredune is the area closest to the beach and is characterized by sand dunes that are closest to the shore. This area is typically exposed to strong winds and salt spray, making it a harsh environment for many organisms. However, some animals have adapted to these conditions and can be found in the foredune, where they may burrow in the sand or feed on the plants that are able to grow in this challenging habitat.
