Answer:
20 large size leaves plants
40 medium sized leaves plants
20 small sized leaves.
Explanation:
PP = large leaves
P'P' = small leaves
PP' = medium leaves
PP' was crossed with another PP' plant:
PP' x PP'
progeny = PP, 2PP', and P'P'
PP = 1/4 x 80 = 20 large size leaves plants
PP' = 1/2 x 80 = 40 medium sized leaves plants
P'P' = 1/4 x 80 = 20 small sized leaves.
<em>Hence the phenotypes would be:</em>
<em>20 large size leaves plants</em>
<em>40 medium sized leaves plants</em>
<em>20 small sized leaves.</em>

Phytoplankton support a wide range of marine life: zooplankton feed on phytoplankton, which in turn support fish and so on.
