Photosynthesis provides radiant energy to all the organisms in the entire food chain.

Photosynthesis is how plants break down glucose to use for energy.

Photosynthesis allows plants to create energy for themselves to store and use for metabolism.

How does the carbon stored in the bodies of living organisms move into rocks?(1 point)

Living organisms decay, releasing carbon into the soil, and soil is compacted into rocks.

Carbon dioxide released through respiration dissolves in certain rocks, like limestone.

Carbon dioxide dissolves in ocean water and is slowly absorbed by rocks in the ocean.

Living organisms decay and become fossils fuels, which eventually become rocks.

The nitrogen cycle requires _____ to convert nitrogen to nitrites and nitrates.(1 point)

bacteria

legumes

animals

plants

The three steps of the nitrogen cycle in order, starting with nitrogen gas in the atmosphere, are(1 point)

nitrification, nitrogen fixation, and denitrification.

nitrogen fixation, nitrification, and denitrification.

denitrification, nitrification, and nitrogen fixation.

Matter flows in one direction, and energy cycles through the environment.

Energy and matter cycle through the environment.

Which statement is true?(1 point)

Food chains are the best depictions of feeding relationships because they show many ways that plants and animals are connected.

Food webs are the best depictions of feeding relationships because they show many ways that plants and animals are connected.

Food chains are the best depictions of feeding relationships because they show a simplified path for the flow of energy through an ecosystem.

Food webs are the best depictions of feeding relationships because they show a single path for the flow of energy through an ecosystem.

The rest are essay questions which I do not need assistance with, thank you to anyone who is kind enough to help (if so, anyone who sees this, please try to help if you know the answers :>)

  35. Answer #12
    Plants recycle matter in nature when they perform photosynthesis and cellular respiration. Carbon, oxygen, and hydrogen atoms are recycled.

    I also wanted to help a little bit instead of just copying answers lol

  36. Answer #13
    Because only about 10% of the energy in a level moves from one level to the next. The rest of the energy, about 90%, is used by organisms in that level to power their metabolism. In addition, some energy at each level is lost to the environment as heat.Plants form the critical base of food chains in nearly all ecosystems. Through photosynthesis, plants harvest the energy of the sun, providing both food and habitat for other organisms.
