What is a producer in an ecosystem?

Back

A producer is an organism, typically a plant or algae, that can make its own food through photosynthesis, serving as a primary source of energy for other organisms in the food web.

Front

What is a food web?

Back

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

Front

What is the 10% rule in ecology?

Back

The 10% rule states that only about 10% of the energy from one trophic level is passed on to the next level in a food chain, while the rest is lost as heat or used for metabolic processes.

Front

What does the direction of arrows in a food chain represent?

Back

The arrows in a food chain indicate the direction of energy flow, showing which organism is consumed by another.

Front

What is an endangered species?

Back

An endangered species is a type of organism that is at risk of extinction and requires conservation efforts to survive.

Front

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance, playing a critical role in maintaining the structure of an ecological community.

Front

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new environment, can cause harm to the ecosystem, economy, or human health.

Front

What factors can cause a population to decrease?

Back

Factors that can cause a population to decrease include predation, disease, loss of habitat, and lack of food resources.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients from producers to various levels of consumers.

Front

What is the role of consumers in an ecosystem?

Back

Consumers are organisms that obtain energy by feeding on other organisms, including herbivores (primary consumers), carnivores (secondary consumers), and omnivores.
