Answer:

Yes

Explanation:

A female frog is able to lay eggs only when the level of estrogen is at the highest level in the body. However both male and female release sperm and egg simultaneously at the same time in order to induce high mating probability. Both male and female acquire a mating posture known as as amplexus which enhances the level of estrogen in females and they thus release their egg .

The plants in a red-tailed hawk’s food chain produce 3 million kcal of chemical energy per day. How much energy is available to

KATRIN_1 [288]

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.
