Answer
:Photosynthesis can be explained in four simple steps, as follows.
Step 1:
The plant gathers sunlight from the chlorophyll in the cells to convert into energy.
Step 2:
The light energy then reactions and forms hydrogen and oxygen.
Step 3:
The hydrogen joins with carbon dioxide and create sugars.
Step 4:
The sugar is then separated, some to be used as the structure in the cell wall, and some stored in the ATP for later use.

Fish will mainly feed on small insects, crustaceans, leeches, worms, zooplankton, algae, and smaller fish.
The manila grasshopper has several benefits to ecosystem and humans.
- In general it facilitates decomposition and regrowth of plants by creating a balance between the types of plants that grow well.
- Like other animals, grasshopper eats and excretes in the soil. Its waste increases the fertility of the soil and promotes plant growth.
- Grasshopper body is rich in protein, on its death microorganisms break down its body and enrich the soil and helps plants to grow.
- Grasshoppers prevent over growth of plants as it consume about 10% of the available plant biomass, thus maintain ecological balance.
