Using the 10 percent rule, explain why there is typically smaller populations of quaternary consumers compared to primary consum

grandymaker [24]

Answer:

As we know 10% law is transfer of energy from higher trophic level to lower trophic level. So as the energy are transfer from one organism to another there is a loss of energy as that energy are utilised by the oragnism and only 10% of the total energy is transferred to the second consumer.

Explanation:

Quetinary consumer are at the higher position in the food chain so they do not get enough energy from prey they have to feed on several organism for the enegy. And also they are at the top of the food chain so they are not eaten by other animal, their life span are also more than primary consumer.

In other hand primary consumer get enough energy but they are prey for other higher tropic level.

Primary and secondary consumer are maintend in such a way by the nature thats make a ecological balance of the habitant.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of

natali 33 [55]

The correct option is (a) 2 → 4 → 1 → 3

A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.

<h3>What is genetic variation in population?</h3>

The presence of various alleles, or different gene versions, within a population indicates genetic variety.
If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
