Front

What is Parasitism?

Back

A relationship between two organisms where one organism benefits at the expense of the other, often harming it.

Front

What is the uppermost trophic level in a trophic pyramid?

Back

The level that contains the top predators in an ecosystem, such as eagles.

Front

What happens to habitats when humans clear forests for development?

Back

Many organisms will lose their homes because their habitats have been destroyed.

Front

What is the effect of introducing a nonnative species into a stable ecosystem?

Back

The native species will have to compete for resources with the nonnative species, leading to an unbalanced ecosystem.

Front

How much energy is transferred from a rose to a falcon in a trophic level?

Back

If a rose receives 10,000 Joules of energy from the sun, only about 10 Joules is available to the falcon.

Front

Define a Trophic Level.

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients.

Front

What is the role of producers in an ecosystem?

Back

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

Front

What is the difference between competition and predation?

Back

Competition occurs when two species vie for the same resources, while predation involves one species hunting and consuming another.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity enhances ecosystem resilience, productivity, and stability.
