Answer:

B. False

Explanation:

Life history characteristics and survivorship patterns within a species are pre-set but may be changed according to the changes in environmental conditions needed for growth and reproduction. Allocation of energy to reproduction or other processes varies according to food availability, temperature, rainfall, etc.  

Abundant resource availability favors the production of a large number of smaller offspring while limited resources make a population to produce a small number of larger progeny to increase the survival rate.  

Example: Clutch size in birds is adjusted to obtain the maximum survival of progeny.

Peat is a mixture of partially decomposed plant and animal material found in waterlogged, acidic, anaerobic environments. people
Verizon [17]

because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.

<h3>What exactly are fossil fuels?</h3>

Fossil fuels are fuels derived from the remains of dead plants and animals that decomposed over time under intense heat and pressure.

Because their replenishment time is longer than a human lifetime, fossil fuels are non-renewable energy sources.

Some examples of fossil fuels are petroleum, coal, etc.

The missing options of the question are:

  1. peat is a fossil fuel because rewetting it takes only 3-5 years.
  2. peat is a fossil fuel because the total time for restoration is lengthy.
  3. peat is not a fossil fuel because it has biologic origins, making it a biofuel.
  4. peat is not a fossil fuel because humans can promote the replenishment of peat.

The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.

Thus, the correct option is B.

ikadub [295]
<span>This theory is called punctuated equilibrium. In this theory it is explained that there are very long periods of no change at all to a species, yet there are also bursts of evolutionary change interspersed within the time period. The period of remaining the same throughout time (most of the time) is called stasis, and is present within this theory of punctuated equilibrium.</span>
