Front

What organisms are likely to increase in population if the Texas horned lizard population decreases due to disease?

Back

Ants and grasshoppers are likely to increase in population.

Front

What component can be added to a model of the carbon cycle to reduce carbon dioxide concentration?

Back

Plants can be added to absorb carbon in the process of photosynthesis.

Front

What is the approximate energy incorporated into the tissues of herbivores if producers incorporate 12,000 kJ of energy from the sun?

Back

Approximately 1,200 kJ of energy would be incorporated into the tissues of herbivores.

Front

What role do producers play in an ecosystem?

Back

Producers convert solar energy into chemical energy through photosynthesis.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

How does a decrease in a predator population affect the populations of prey species?

Back

A decrease in predator population can lead to an increase in prey species populations.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms.

Front

What is the significance of energy transfer in an ecosystem?

Back

Energy transfer is significant because it determines the structure and function of the ecosystem, affecting population dynamics.

Front

What is the primary source of energy for producers in an ecosystem?

Back

The primary source of energy for producers is sunlight.

Front

What is the relationship between herbivores and producers in an ecosystem?

Back

Herbivores depend on producers for food and energy.
