Answer:
c. the cost to growth of allocating resources to defense
d. consistent fitness benefits of high allocations to defense
Explanation:
In order to ensure survival by escape of grazing and browsing by herbivores (and insects) plant usually adopt different defence mechanisms.This forms the basis for the optimum defence hypothesis .
The basic idea of the hypothesis is that the type of defence that an organism e.g plant will adopt against an herbivore depends on its fitness, and since this involve expenditure of energy it will be expensive for the organism to afford and maintain.
Q#1
- Carnivorous plants decoy insects by sweet scent or color.
- Not expecting threats insects sit on the plant. This catches them using mechanical traps or sticky substances.
- Then, the plant produces digestive enzymes that break down proteins, fats and sugars which make up the body of the victims for simple compounds which plant can absorb.
Q#2. Carnivorous plants grow in mineral-poor soil, raise substances necessary for life from the bodies of trapped animals. They hunt animals, so that the surface on which they grow, no nutrients they need.
Q#3.Plants by digesting insects provide each large dose of nitrates are lacking in the soil.
Q#4.<span>When a pitcher plant is grown in nitrogen rich soil it grows tall. Insects are it's food source so if it doesn't get any food, it will starve. </span>
