What is a microsatellite in genetics?

Back

A microsatellite is a repeating sequence of DNA that can be used to compare genetic variation among individuals or populations.

Front

What is the significance of DNA bands in genetic comparison?

Back

DNA bands represent different alleles or genetic markers that can indicate genetic relationships among individuals.

Front

What is the primary consumer level in an ecosystem?

Back

The primary consumer level consists of herbivores that eat producers (plants) and convert the energy stored in them.

Front

How much energy is typically transferred from producers to primary consumers?

Back

Typically, only about 10% of the energy from producers is transferred to primary consumers.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process by which nitrogen in the atmosphere is converted into ammonia or related compounds in soil, making it available for plants.

Front

Why can't plants and animals use atmospheric nitrogen directly?

Back

Plants and animals cannot use atmospheric nitrogen directly because it is in a gaseous form (N2) that they cannot metabolize.

Front

What do plants absorb from the soil to obtain nitrogen?

Back

Plants absorb nitrates from the soil, which are a form of nitrogen that they can use for growth.

Front

What role do herbivores play in an ecosystem?

Back

Herbivores serve as primary consumers that convert plant energy into energy for higher trophic levels.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the flow of energy and nutrients through an ecosystem.

Front

What is the difference between primary and secondary consumers?

Back

Primary consumers are herbivores that eat producers, while secondary consumers are carnivores that eat primary consumers.
