1 Trophic levels energy and pyramids

Front

What are trophic levels?

Back

Trophic levels are the hierarchical levels in an ecosystem, representing the flow of energy and nutrients from one level to another, typically categorized as producers, primary consumers, secondary consumers, and tertiary consumers.

Front

What is the role of producers in an ecosystem?

Back

Producers, also known as autotrophs, are organisms that create their own food through photosynthesis or chemosynthesis, forming the base of the food chain.

Front

Define primary consumers.

Back

Primary consumers are herbivores that eat producers (plants) and are the second trophic level in the food chain.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers (herbivores) and are typically carnivores or omnivores.

Front

What is the difference between carnivores and herbivores?

Back

Carnivores are animals that primarily eat other animals (meat), while herbivores are animals that primarily eat plants.

Front

What is an omnivore?

Back

An omnivore is an organism that eats both plants and animals, allowing it to occupy multiple trophic levels.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how different organisms in an ecosystem are related through feeding relationships.

Front

What is energy transfer in trophic levels?

Back

Energy transfer in trophic levels refers to the movement of energy from one level to the next, with only about 10% of the energy being passed on to the next level due to energy loss through metabolic processes.

Front

What is a pyramid of energy?

Back

A pyramid of energy is a graphical representation that shows the amount of energy available at each trophic level in an ecosystem, typically decreasing as you move up the pyramid.
