Answer:
c. limiting factor.
Explanation:
The limiting factors are environmental or ecological factors that act directly on the living beings of a population, limiting their size, since these factors determine their birth, mortality, migrations, etc. They are the ones that regulate the growth and expansion of a species.
If environmental factors are optimal for the development of a living being, they favor the growth of that organism in that biotope. But if any of these factors prevents the growth of a species, there is talk of a limiting factor.
Among these physical and chemical factors that determine the biotope include:
- Abiotic factors (do not depend on population density):
Climate:
Light. Only the most superficial organisms access it in water. On land, there is also competition in leafy areas to access it.
Temperature. Some living beings cannot live at the temperature that others live.
Water: It is necessary that it rains or that living beings can access water in order to live. If there is no water, they die.
Atmospheric pressure.
Non-climatic:
Soil factors: The chemical composition of the soil, its pH, salinity, etc. It makes some plant species may or may not survive in it.
Factors of the aquatic environment: The concentration of O2, dissolved CO2, the degree of salinity, the existence of currents, etc., limits the development of some organisms.
- Biotic factors (depend on population density):
Food. If they do not have enough food, the population will have to be smaller.
Interspecific relationships. The number of predators limits the number of prey, and vice versa.
Intraspecific relationships. The relationships established between individuals of the same species can also limit their existence.

Answer:
mutualism
Explanation:
Mutualism is a type of symbiotic relationship between two organisms in which both benefit and neither is affected negatively in any way.
Mutualism can be in the form of resource-resource when it involves an exchange of resources between the organisms, service-resource when a resource is being swapped for a service or, service to service when it involves exchange of services between the two organisms.
In this case, the clownfish offers protection service to the sea anemone while the sea anemone in turn also offers protection to the clownfish. This is a service-service mutualism.
b. stratosphere
c. mesosphere
d. thermosphere
Auroras occur in the "thermosphere".
The thermosphere lies between the exosphere and the mesosphere.It is a district of expanding temperature in Earth's climate that is situated over the mesosphere.
The thermosphere significantly helps in ensuring the earth and making space investigation and present day types of correspondence conceivable. It additionally supports and ensures life on the planet. It reuses water, retains the sun's energy, and makes a moderate temperature.
The aurora (Northern Lights and Southern Lights) generally present in the thermosphere. It is a natural electrical marvel described by the presence of streamers of rosy or greenish light in the sky, particularly close to the northern or southern attractive shaft. The impact is caused by the communication of charged particles from the sun with iotas in the upper atmosphere.
Auroras occur in the thermosphere. Therefore, the correct option is D.
The Northern Lights, or aurora borealis, and the Southern Lights, or Aurora Australis, are natural light displays that occur in Earth's upper atmosphere. The thermosphere, the uppermost part of Earth's atmosphere, is where most of them occur. Several hundred kilometers to about 80 kilometers (50 mi) above the Earth's surface is where the thermosphere begins. Auroras are generated when charged solar particles such as electrons and protons interact with Earth's magnetic field and strike atoms and molecules in the thermosphere.
Therefore, the correct option is D.

Answer:
CUAAUGU
Explanation:
Phototropism benefits plants by allowing them to grow towards a light source, maximizing their exposure to sunlight for photosynthesis.
Phototropism is light-induced plant growth. It helps plants adapt in several ways. First, phototropism helps plants maximise sunshine exposure, which is essential for photosynthesis. Plants can maximise light absorption and photosynthetic efficiency by bending or growing towards light.
Phototropism aids plant light competition. Plants compete for light in dense vegetation or woods. Plants can maximise sunlight and minimise shadowing from neighbouring plants by growing towards light.
Phototropism helps plants maximise light energy use, growth, and survival in their ecological niche.
