Module 1a Review

Front

What is a marine food pyramid?

Back

A marine food pyramid is a graphical representation of the energy flow in a marine ecosystem, showing the different levels of producers, consumers, and decomposers.

Front

Between which two levels of a marine food pyramid is the greatest amount of energy transferred?

Back

The greatest amount of energy is transferred between the levels U and T.

Front

What are limiting factors in an ecosystem?

Back

Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of an organism or a population within an ecosystem.

Front

What is an abiotic factor?

Back

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

Front

Give an example of an abiotic factor in the desert.

Back

Sunlight is an example of an abiotic factor in the desert.

Front

What happens to a bird population if its food source decreases due to disease?

Back

The bird population would decrease if its food source, such as barley plants, is affected by disease.

Front

What percentage of energy is lost as heat or used by organisms for survival in an energy pyramid?

Back

90% of energy is lost as heat or used by organisms for survival in an energy pyramid.

Front

Define carrying capacity.

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Front

What is the role of producers in a food chain?

Back

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

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a complex network of interconnected food chains.
