Explanation:
The net primary productivity tells us about how productive an ecosystem is. It is usually derived by the difference between the amount of carbon dioxide that producers used to the amount they release during their cellular respiration.
- The rainforest is the biome with the highest amount of net productivity.
- The amount of sunlight and organic matter used up during photosynthesis is very large.
- The tropical rain forest receives the highest amount of sunlight because the sun is overhead here.
- This provides energy to drive photosynthetic process in the presence of other available resources.
- Deserts are bare and lacks plants due to the extreme conditions here not favorable to life.
- The open ocean productivity is restricted to the photic zone where light is only able to reach
- Lakes are highly productive ecosystems.

Answer:
Step 1: Inhibition: water fills the seed.
Step 2: The water activates enzymes that begin the plant's growth.
Step 3: The seed grows a root to access water underground.
Step 4: The seed grows shoots that grow towards the sun.
Step 5: The shoots grow leaves and begin photomorphogenesis.
Explanation:
Assuming seed germination.
The core of a star must react a temperature of 10,000,000 degree Celsius for hydrogen fusion to begin
Explanation:
A star formed from a rotating cloud which is made up with completely with helium and hydrogen. The gravitational force pulls the cloud behind to collapse inward and due to this it shrinks and later it spins more and more quickly with the outer parts.
When the core and inner part become a rough spherical clump then it becomes disk. The star life cycles follow the patterns which is based on mostly on their initial mass.
