What is a Primary Consumer?

Back

A Primary Consumer is an organism that eats producers (plants) in a food web. They are typically herbivores.

Front

What does 'K' represent in ecological graphs?

Back

'K' represents the carrying capacity, which is the maximum population size that an environment can sustain.

Front

How do animals release carbon back into the carbon cycle?

Back

Animals release carbon through respiration and decomposition.

Front

What are CFCs and their impact on the environment?

Back

CFCs (Chlorofluorocarbons) are compounds that cause ozone depletion in the stratosphere.

Front

What is a Trophic Level?

Back

A Trophic Level is each step in the transfer of energy and matter within a biological community.

Front

Define Decomposer.

Back

Decomposers are organisms that break down dead organic material, returning nutrients to the soil.

Front

What is the role of Producers in an ecosystem?

Back

Producers are organisms that create their own food through photosynthesis, forming the base of the food web.

Front

Explain the Carbon Cycle.

Back

The Carbon Cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms.

Front

What is the difference between a Predator and Prey?

Back

A Predator is an organism that hunts and eats other organisms (Prey) for food.

Front

What is Exponential Growth in population ecology?

Back

Exponential Growth occurs when a population increases rapidly due to abundant resources, leading to a J-shaped curve.
