Why do we need to protect ecosystems?
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies.
How can we protect ecosystems?
Ten Simple Things You Can Do to Help Protect the Earth
- Reduce, reuse, and recycle. Cut down on what you throw away.
- Volunteer. Volunteer for cleanups in your community.
- Educate.
- Conserve water.
- Choose sustainable.
- Shop wisely.
- Use long-lasting light bulbs.
- Plant a tree.
Why is photosynthesis so important to ecosystems?
It provides energy for nearly all ecosystems. By transforming light energy into chemical energy, photosynthesis provides the energy used by organisms, whether those organisms are plants, grasshoppers, wolves, or fungi.
What is difference between photosynthesis and respiration?
The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.
Where does photosynthesis mostly happen?
chloroplasts
In which plant organ does photosynthesis most commonly occur?
What is the result of photosynthesis?
In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced.
What are the two main byproducts of photosynthesis?
In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Where is oxygen formed from as a result of photosynthesis?
The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. The electrons that freed from the water are transferred to ATP and NADPH.
