Answer 2

-Optimal conditions are those that provide optimal fitness

Question 3

Fundamental and realised niche:

-The theoretical habitat, not always occupied due to competing species

Realised Niche:
-Set of conditions used by an organism after including interactions with other species
-The actual habitat that is occupied by an organism in the presence of competing species

Question 4

Temperature-size rule:

Answer 4

-Final size of an organism decreases with increasing temperature during development

Question 5

Thermoneutral zone:

Answer 5

-For endotherms regulating body temperatures requires a large amount of energy
-Over a certain temperature range, known as the thermoneutral zone, an endotherm consumes energy at a basal rate
-But at environmental temperatures above or below that zone, the endotherm consumes more energy to maintain the constant body temperature
