</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>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:
A) a cow who's coat color is roan (red and white) : Co- dominance
B) A red flower and a white flower produce a pink flower: Incomplete dominance
C) In rabbits there are 4 different versions of the gene for coat color- Multiple alleles
Explanation:
Co-dominance can be described as a phenomenon in which the two different phenotypes of the parents can be seen in the offspring produced by them. For example, In the option A, the cow had a parent with red coat colour and a parent with a white coat colour. Both these traits were seen in the offspring.
Incomplete dominance is a phenomenon in which parents of two different phenotypes give rise to a new phenotype in the offspring which is not present in both of the parents.
