Answer:
The correct answer is - 2) density-independent limiting factor.
Explanation:
Density-independent limiting factors are the factors that cause a change in the size of the population without getting influenced by the density of the population.
Density-independent limiting factors include biotic or abiotic factors with catastrophic conditions such as natural disasters such as floods, earthquakes, drought, fires, and many more.
Drought affects the size of the population by increasing competition in the ecosystem for resources.
The sun is the primary source of energy for living things mostly organisms like plants and ecosystems. But if you're talking about the bonds inside organic molecules, which are carbohydrates. With this, the energy from the sun gets trapped within a chemical bond and still relates to photosynthesis in plants.
Answer:
Predator prey
Explanation:
Animals that feed on other animals are called predators and the animals they eat are called prey. All predators have specific interactions with their prey as they are locked in an evolutionary "arms race". The prey will try to develop novel traits to survive as the predators will try to adapt to these. This is not a conscious process, but rather an evolutionary one, where prey individuals that have a survival advantage will survive and thus reproduce more.
The second image illustrates a predator-prey cycle where an increase in the prey numbers will lead to an increase in the predator numbers. This in turn will lead to a decrease in the prey number which in turn will also lead to a decrease in the predator's numbers.
The third image is a trophic or ecological pyramid in which X are the primary producers (ex. plants), Y are the animals that feed on these (prey) and Z are the predators that feed on Y. In general, top predators are not hunted and eaten by other species which is why they are at the top of the pyramid.
A. Photosynthesis to generate energy
