EOC Review #5 (Ecology & Evolution)

Front

What is the original source of almost all energy in most ecosystems?

Back

Sunlight is the primary source of energy for most ecosystems, driving photosynthesis in plants.

Front

Which organism in the food web would contain the highest concentration of chemical pollutants?

Back

Tertiary consumers accumulate the highest concentration of chemical pollutants due to biomagnification.

Front

What are the physical remains of a plant or animal preserved in rock or Earth's crust called?

Back

Fossils are the preserved remains or traces of ancient organisms.

Front

On a cladogram, which organism is the closest relative of humans?

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What is biomagnification?

Back

Biomagnification is the process where the concentration of toxins increases in organisms at higher trophic levels.
