What is deforestation?

Back

Deforestation is the process of clearing or removing forests or trees, often to make way for agricultural activities or urban development.

Why do energy pyramids typically have only 3 or 4 trophic levels?

Back

Energy pyramids have only 3 or 4 trophic levels because energy is lost at each level due to metabolism and heat, limiting the number of levels that can be supported.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is mutualism in ecology?

Back

Mutualism is a type of symbiotic relationship in which both organisms involved benefit from the interaction.

Front

What does an S-curve represent in population ecology?

Back

An S-curve represents a population that has reached its carrying capacity, showing a period of rapid growth followed by stabilization.

Front

What is carrying capacity?

Back

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

Front

What is the significance of energy flow in an ecosystem?

Back

Energy flow is significant in an ecosystem as it determines the productivity and health of the ecosystem, influencing the structure and function of food webs.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and making them available for producers.
