The two most important climatic factors that influence ecosystems are:

Wind and temperature
Food and temperature
Wind and availability of water
Sunlight and availability of water

Correct Answer

A. Sunlight and availability of water

Explanation

Sunlight and availability of water are the two most important climatic factors that influence ecosystems. Sunlight is essential for photosynthesis, the process by which plants convert sunlight into energy. It also determines the temperature and provides energy for the ecosystem. Availability of water is crucial for the survival of all organisms as it is necessary for various physiological processes. Water availability affects the distribution and abundance of species, as well as the overall productivity of the ecosystem. Therefore, sunlight and availability of water play a vital role in shaping and sustaining ecosystems.

Bacteria and Fungi that decompose dead plant and animal matter are called...

Carnivores
Herbivores
Detritivores
Nasty little buggers!

Correct Answer

A. Detritivores

Explanation

Detritivores are organisms that break down dead plant and animal matter, such as bacteria and fungi. They play a crucial role in the ecosystem by recycling nutrients back into the environment. Unlike carnivores and herbivores, which obtain energy by consuming living organisms, detritivores obtain energy from organic material that is already dead. Therefore, the correct answer for this question is detritivores.

An organism's habitat is described as...

Its location
Its role in the ecosystem
Its role in the ecosystem and its location
None of the above

Correct Answer

A. Its location

Explanation

The correct answer is "its location." An organism's habitat refers to the specific place or area where it lives, including the physical environment and the resources available to it. It is primarily determined by the organism's location, such as a forest, ocean, or desert, which provides the necessary conditions for the organism to survive and thrive. The other options, "its role in the ecosystem" and "its role in the ecosystem and its location," are not accurate as they do not fully encompass the concept of habitat.

As you move up a trophic level...

Energy is lost according to the first law of thermodynamics
You move further away from the autotrophs
There is a decrease in biomass
All of the above

Correct Answer

A. All of the above

Explanation

As you move up a trophic level, all of the above statements are true. According to the first law of thermodynamics, energy is lost as it moves up the food chain, resulting in a decrease in available energy. Moving further away from the autotrophs means moving away from the primary producers, which are the organisms at the bottom of the food chain. This implies that as you move up the trophic levels, you are getting further away from the autotrophs. Additionally, there is a decrease in biomass as you move up the trophic levels since energy is lost and not all of it is transferred to the next level.

The bunnies at LBCC are known as _________________ in the trophic structure?

Producers
Predators
Prey
Consumers

Correct Answer

A. Consumers

Explanation

The bunnies at LBCC are known as consumers in the trophic structure because they feed on plants and other organisms to obtain energy. Consumers are organisms that cannot produce their own food and rely on consuming other organisms for survival. In this case, the bunnies consume plants or possibly other small animals, making them consumers in the trophic structure.

Biomes are maintained by

The government
Climate
Animals
Plants

Correct Answer

A. Climate

Explanation

Biomes are maintained by climate because climate plays a crucial role in determining the types of plants and animals that can survive in a particular area. Climate influences factors such as temperature, precipitation, and sunlight, which in turn affect the availability of resources and the overall conditions for life. Different climates support different types of vegetation and wildlife, leading to the formation and maintenance of distinct biomes around the world. Therefore, climate is a fundamental factor in shaping and sustaining biomes.
