3.4 FLASHCARD - Biomass Pyramids & Matter Cycles

Front

What is a biomass pyramid?

Back

A biomass pyramid is a graphical representation that shows the relative amount of biomass at each trophic level in an ecosystem.

Front

What processes are involved in the water cycle?

Back

The water cycle includes processes such as evaporation, condensation, precipitation, and transpiration.

Front

What role do producers play in the carbon-oxygen cycle?

Back

Producers generate oxygen through photosynthesis and utilize carbon dioxide.

Front

Why are decomposers important in a food chain?

Back

Decomposers return nutrients to the ecosystem by breaking down dead organic matter.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, involving processes like nitrogen fixation and nitrification.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and then released as vapor through pores in leaves.

Front

What is the significance of bacteria in the nitrogen cycle?

Back

Bacteria play a crucial role in the nitrogen cycle by carrying out processes such as nitrogen fixation and decomposition.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of liquid water turning into vapor, while condensation is the process of vapor turning back into liquid water.

Front

What is the role of consumers in an ecosystem?

Back

Consumers obtain energy by eating other organisms, and they play a vital role in transferring energy through the food chain.

Front

What is the function of scavengers in an ecosystem?

Back

Scavengers consume dead animals and help in the decomposition process, contributing to nutrient cycling.
