Food Chains, Energy Pyramids and Carbon Cycle

Front

What are autotrophic organisms?

Back

Autotrophic organisms are those that can make their own energy, typically through photosynthesis or chemosynthesis. Examples include plants and some bacteria.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants). They are usually herbivores, such as rabbits or deer.

Front

What is the role of producers in a food chain?

Back

Producers, like plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between organisms.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms, involving processes like photosynthesis and respiration.

Front

How do herbivores differ from carnivores?

Back

Herbivores primarily eat plants (producers), while carnivores eat other animals (consumers).

Front

What happens to energy as it moves up a food chain?

Back

As energy moves up a food chain, it decreases at each trophic level due to energy loss through metabolic processes.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation showing the flow of energy at different trophic levels in an ecosystem, with producers at the base and top predators at the apex.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth.

Front

How does sunlight affect food production in an ecosystem?

Back

Sunlight is essential for photosynthesis, allowing producers to create food. A lack of sunlight can disrupt food production and the entire food web.
