Sunlight, water, carbon dioxide
Answer:
Grasslands and herbivores have a mutually beneficial symbiotic relationship. If larger herbivores such as Kangaroos and Elephants are removed from them, they may become extant.
Explanation:
Herbivores are always hungry and they are always looking for ways to replenish lost energy. Between tree shoots and grass, they often go for the former because they are tender, easier to reach, and less difficult to masticate than the young tree shrubs.
When baby trees become bigger, their shade prevents adequate sunlight from reaching the grass, then gradually they become scanty or subdued for as long as the shade remains.
When large herbivores are removed or leave a grassland, trees have the ability to flourish. Then the results indicated above happens.

Answer:
0.8 and 0.2
Explanation:
Hardy Weinberg law states that the allele frequency of the population remain stable from one generation to next generation if no natural selection, drift or mutation occurs in the population.
Let p and q be the dominant and recessive frequency of the population respectively.
The dominant phenotype means p² = 0.64
p = 0.8
and we known that p + q = 1, in hardy Weinberg equilibrium.
0.8 + q = 1.
q = 0.2
Thus, the dominant allele is 0.8 and recessive allele is 0.2.
