At midnight, what process are the cells of a plant doing?

cellular respiration

What do decomposers do for the environment

they convert large molecules into simpler molecules that can then be recycled

is fog a form of precipitation

no

what are all living things made up of

carbon

Is carbon the most abundant element in the universe

no

what does burning fossil fuels do with carbon dioxide

resleases more of it into the atmosphere

what does denitrifying bacteria do

return nitrogen to the atmosphere

What is an organism that eats producers or other consumers called

heterotroph (consumer)

What is a population

All the members of the SAME SPECIES living in the same ecosystem

What is a community

The collection of ALL THE POPULATIONS of the DIFFERENT SPECIES in an ecosystem

what is an ecosystem

what is the word equation for photosynthesis

carbon dioxide+water+sunlight—>oxygen+sugar

what is the word equation for cellular respiration

glucose+oxygen—>carbon dioxide+water+energy

What happens in the carbon cycle

carbon atoms travel between four reservoirs

atmosphere, land, oceans, living organisms

plants absorb it from the atmosphere

animals get it from eating plants

fossil fuels combust to get released into the atmosphere

what happens in the nitrogen cycle

moves through atmosphere, soil, water, living organisms

bacteria fixes the atoms into plant roots

Animals can get the nitrogen from eating the plants

when biotics die the nitrogen returns to the soil

denitrifying bacteria returns the nitrogen into the atmosphere as a gas
