<span>a)
</span>The milkweed is the primary producer in the
ecosystem. It manufactures food from the abiotic factors in the soil such as
nitrates and water and those in the atmosphere such as carbon-dioxide and
sunlight. The milk weed is then fed on by the caterpillar and a primary
consumer. The caterpillar is then fed on the mocking bird (secondary consumer)
<span>b)
</span>Increased human population growth and their activities
have resulted in the emission of carbon dioxide and other greenhouse gases in
the atmosphere. This has increased the global temperature. This increase of
global temperature increase ocean temperatures causing coral bleaching.
Another example is depletion of water sources
by human activities hence causing drought. Drought reduces the amount of
vegetation growth due to scarcity of water in the soil (due to lowering of the
water table) for plant growth.

Answer:
An orange peel in a trash will start to decompose.
- The carbon atoms will be released into the air as a result of decomposition.
- These carbon atoms will be converted into carbon dioxide in the atmosphere.
- Plants will take in this carbon dioxide for making food by the process of photosynthesis.
- When animals will consume the pants, the carbon products will be accumulated int he body of the animals. Some of the carbon will be converted into carbon dioxide in the animals and will pass out of the animal's body through respiration.
Mitochondria convert the energy in the bonds of glucose and oxygen to readily available energy in the form of ATP (Adinoshin Tri Phosphate) with the help of oxygen. Mitochondria are often referred to as the powerhouse of cell.
