Question

1. how are cellular respiration and photosynthesis almost opposite processes?a. photosynthesis stores energy, and cellular respiration releases energy.b. photosynthesis adds carbon dioxide to the atmosphere, and cellular respiration removes carbon dioxide to the atmosphere.c. photosynthesis removes oxygen from the atmosphere, and cellular respiration adds oxygen to the atmosphere.answerdescribe how energy and matter (atoms) move through ecosystems differently.use the words: energy, matter, recycle, flow

Explanation:

For question 12: Photosynthesis converts light energy to stored chemical energy, while cellular respiration releases that stored energy for cell use. Photosynthesis takes in carbon dioxide and releases oxygen, while cellular respiration takes in oxygen and releases carbon dioxide, making them nearly opposite processes.
For the second question: Matter (atoms) is recycled through ecosystems as organisms take in, use, and release atoms that are reused by other organisms. Energy flows in one direction through ecosystems, entering as light energy, converted to chemical energy, passed between organisms, and lost as heat, with no recycling of energy.

Answer:

1. a. Photosynthesis stores energy, and cellular respiration releases energy.

Photosynthesis and cellular respiration are almost opposite processes.
---
Matter (atoms) is recycled through ecosystems: atoms are taken up by organisms, used to build or break down molecules, and released back into the environment to be reused by other living things. Energy flows in a one-way path through ecosystems: it enters as light energy, is converted to chemical energy by producers, transferred to consumers, and is eventually lost as heat, with no recycling of energy.
