Answer:
age-graded
Explanation:
Age-graded influences are biological and environmental events that influence the dynamic interaction between an individual and their environment at certain ages of the individual’s course of life. They are events that are expected to occur in a particular setting based on chronological age. For example, depending on the cultural settings of an individual, an individual is expected to graduate high school at a certain age, or get married at a certain age. Another example is puberty and menopause which are biological influences that are age-graded.
The amount of total energy at each trophic level decreases as it moves through, so 90% is lost at each level. This means that only 10 percent of the energy at any trophic level is transferred to the next level; and the rest is lost as heat.
In this case, if a plant ecosystem has 3000000 kilocalories (kcal) of energy, about 300000 kcal will be transferred to primary consumers (for example grass hoppers). If the red-tailed hawks are tertiary consumers, they will get 3000 kcal of energy.
