Loss of biodiversity affects the ecosystem in many ways. For example, if a species disappears, the animals/plants that it fed on will suddenly increase in population due to loss of predators. The predators of the lost species, however, will go down in population because its main source of food has disappeared.
They have to adapt to the water, the animals in the ocean, the way they hear and see.
Considering the following statements;
A. The trait is the same for all organisms
B. The trait is resistant to mutations
C. Most forms of the trait have the same impact on survival
D. The trait is passed on genetically to the next generation
The correct answer is D.
Genetic variation is essential for natural selection since natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by mutation and random mating organisms.
A gametophyte is a multicellular haploid that is formed from the spore. It is true that the life cycle alternates from haploid to diploid.
