use an example to explain how timing of reproduction in plants and animals is tied to energy availability
alisha [4.7K]

All animals and plants have evolved to time the periods of their reproduction in accordance to the available resources, or rather they are more abundant and easier to get.

Explanation:

As examples we can take the apricot tree, as a plant, and the lynx, as an animal.

The apricot tree starts the process of reproduction when the temperatures are higher and when there is more sunlight. This usually starts from the beginning or middle of March. The reason as to why the apricot starts the reproduction during this period is because the warmer weather enables the bees to come out and pollinate it, while the sunlight is crucial because as a plant the apricot uses it for the process of photosynthesis.

The lynx is member of the cat family. It is a predator so it has timed its reproduction in accordance to the reproduction of its prey. The reason for this is that the lynx will need more food when it has cubs, so it is much easier to get more food when its prey has offspring as well as they are easy target, but also the mothers tend to be more defensive and often try to stand up to the predator which also makes them much easier targets.

OverLord2011 [107]
Hi there
The formula is
A=p (1+rt)
We need to solve for t
T=[(A/p)-1]÷r
Where
A future value 2200
P present value 1000
R interest rate 0.08
T time?
So
T=((2,200÷1,000)−1)÷0.08
T=15 years

Another time like this question you should post in at mathematics subject
