Energy Flow in Ecosystems (10pts.)

Front

What is energy flow in ecosystems?

Back

Energy flow in ecosystems refers to the transfer of energy from one organism to another through food chains and food webs, starting from producers to various levels of consumers.

Front

What are producers in an ecosystem?

Back

Producers are organisms, such as plants and algae, that can make their own food through photosynthesis, serving as the primary source of energy for consumers.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that cannot produce their own food and rely on consuming other organisms for energy. They can be classified as herbivores, carnivores, or omnivores.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, recycling nutrients back into the ecosystem.

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, starting from producers to various levels of consumers.

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 an omnivore?

Back

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

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the organism's role in the flow of energy, such as producers, primary consumers, secondary consumers, and tertiary consumers.

Front

Why is energy transfer in food chains inefficient?

Back

Energy transfer in food chains is inefficient because only about 10% of the energy from one trophic level is passed to the next; the rest is used for metabolic processes or lost as heat.

Front

What happens when a species is removed from a food web?

Back

Removing a species from a food web can disrupt the balance of the ecosystem, potentially leading to population increases or decreases in other species that are directly or indirectly affected.
