1. Phosphorous from the rocks get eroded and the phosphate ion from it seeps into the water and soil.

2. Plants absorb the phosphate from their roots and include it in its nucleic acid.

3. Animals feed on plants and get phosphorous from it.

4. Decomposers breaks down the phosphorous from the animals and release it into the soil which gets reabsorbed by the plants.

How will temperature affect the rate of photosynthesis? Write hypothesis here. (Be sure to relate how rare of photosynthesis wil
balandron [24]

Explanation:

The rate of photosynthesis increases withe increase in temperature. Photosynthesis like any other chemical reaction responds positively to an increase in temperature.

At high temperatures, enzymes that takes part in the photosynthesis can be destroyed. This is 20°C where enzymes are usually denatured.

  • Photosynthesis is the process where green plants manufacture their food using inorganic substances from the environment.
  • During photosynthesis, plants combines carbon dioxide with water and produces organic molecules and oxygen.
  • Like any other chemical reaction, the reaction will proceed faster with an increase in temperature.

Hypothesis: If temperature is increased then the rate of evolution of oxygen gas increases because the rate of chemical reactions increases with increase in temperature.

Since oxygen is a by product of photosynthesis, we can quantify its rate of production as temperature increases.
