Food Webs & Energy Transfer

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

Front

Define biotic factors.

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms.

Front

Define abiotic factors.

Back

Abiotic factors are the non-living components of an ecosystem, such as sunlight, water, temperature, and soil.

What is energy transfer in an ecosystem?

Back

Energy transfer in an ecosystem refers to the movement of energy through food chains and food webs, from producers to consumers and decomposers.

Front

What role do producers play in a food web?

Back

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

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and maintaining the health of the ecosystem.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the atmosphere through small openings in their leaves called stomata.

Front

What is the difference between a population and a community?

Back

A population is a group of individuals of the same species living in a specific area, while a community is made up of different populations of various species interacting in a particular environment.

Front

What happens to energy as it moves up the food chain?

Back

As energy moves up the food chain, it decreases at each trophic level due to energy loss through metabolic processes, heat, and waste.

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, involving processes like photosynthesis, respiration, and decomposition.
