The Competitive Exclusion Principle states that: Group of answer choices a. When two species occur together, competition is alwa
Reika [66]

Answer:

b. Two species that use a limited resource in the same way cannot coexist indefinitely

Explanation:

The competitive exclusion principle establishes that two or more species that share the same niche requirements,  in the same habitat, and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. This is because species with identical niches have the same necessities, which means that they will compete for the same resources. If these species have the same requirements, they can not coexist. When the superior competitor occupies the inferior competitor´s fundamental niche, the first species has advantages over the second species and <em>monopolizes all the resources</em>. From that moment, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs or get extinct.

When <em>two competing species coexist</em>, this is because of niche partitioning or niche differentiation. One of the species uses a <em>different resource, occupies another area, or uses the resources at different times during the day</em>. If there is not any differentiation between them, the dominant species displaces the weak species.

Niche specialization might produce genotypic separation. Subpopulations of a species diverge into new species.    

So, <em>competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche.    </em>

Does specific heat also mean the amount of energy needed for cooling, or is it only energy for heating?
const2013 [10]

Answer:

yes it does

here is a more clearer explanation

Explanation:

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

Some other examples of specific heat capacities are:

Material Specific heat capacity (J/kg/°C)

Brick 840

Copper 385

Lead 129

Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature. Brick will take much longer to heat up and cool down. This is why bricks are sometimes used in storage heaters as they stay warm for a long time. Most heaters are filled with oil (1,800 J/kg°C) or water (4,200 J/kg°C) as these emit a lot of energy as they cool down and, therefore, stay warm for a long time.

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C).

What is the basic difference between waste<br>products and excretory products?​
Schach [20]

Answer:

All waste products are not excretory products but all excretory products are waste products

Explanation:

Every living organism needs oxygen and nutrients for survival. In the process, they discharge products that can no longer be used by their system. These “wastes” can be categorized into two types based on their discharged material. The materials discharged during the process of Egestion are undigested matter leftover from the process of digestion. Excretion, on the other hand, discharges metabolic waste products. This is the main Difference Between Egestion And Excretion.
