Answer:
The density- independent limiting factors that can affect a population include food, predation, toxic waste and environmental disasters.
Explanation:
Density independent factors like <u>natural calamities which include volcanic eruptions, hurricane, floods, earthquake</u>, etc are not influenced by population density change. For example, the current rampaging bush fire in Australia has caused a lot of damage to different animal and plant species. Many populations of species have become endangered and others are wiped off.
The quality of nutrients available in an environment affect the growth of organisms in it. The lower the quality of nutrients, the higher is the environmental stress. E.g in <em>Lake Erie</em>, the growth of algae was restricted due to the extensive presence of phosphorus in the water bodies.
Pollution is also a big reason for decrease in the density of populations. E.g Amphibians such as toad, frog are susceptible to pesticides which flow into the water bodies. It reduces their ability to <em>reproduce</em> and inhibits their growth.
When the number of predators in a given area increase, the population of <em>prey decreases</em>. Extensive predation can lead to the extinction of prey species.
The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.
Answer:
Blue and red
Explanation:
<em>Action spectrum is the region of light that is utilized for photosynthesis by photosynthetic organisms. </em>
According to several research, the rate of photosynthesis in green plants is highest in red region of light, followed by blue region.
<em>If Halobacterium's photosynthetic action spectrum is the opposite of green plants and photosynthetic organisms, it means the rate of photosynthesis in Halobacterium will be highest in blue light, followed by red.</em>
The answer is blue and red.
