Test: Competition and Organism Interaction in Ecosystems

Front

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new environment, can outcompete native species for resources, disrupt ecosystems, and cause harm to the environment.

Front

What is an abiotic factor in an ecosystem?

Back

An abiotic factor is a non-living component of an ecosystem, such as water, sunlight, soil, and temperature, that affects living organisms.

Front

What role do producers play in an ecosystem?

Back

Producers create their own food through photosynthesis and form the base of the food chain, supporting all other organisms.

Front

What happens to populations when a resource is abundant?

Back

When a resource is abundant, populations that depend on it may increase due to the availability of food, water, or shelter.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) to obtain energy, such as herbivores.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers to obtain energy, such as carnivores.

Front

How does competition affect organisms in an ecosystem?

Back

Competition occurs when organisms vie for the same resources, which can limit population growth and affect survival.

Front

What is the food chain?

Back

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

Front

What is biodiversity?

Back

Biodiversity refers to the variety of living organisms in a particular ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What is the impact of a decrease in primary consumers on secondary consumers?

Back

If the primary consumer population decreases, the secondary consumer population is likely to decrease as well due to less available food.
