Ecological relationships describe the interactions between and among organisms within their environment. The can be positive, negative or neutral.

Predation can be considered as any interaction between two species where one species is a bit stronger and benefits by obtaining resources from and to the detriment of the other.

Competition occurs when multiple organisms compete for a limited resource that they all need to survive.

Mutualism is a positive interaction that benefits two different species in the community. For example, the mutualistic relationship between alga and fungus that form lichens creating a new beneficial species in the community.

Commensalism is an interaction where one species benefits and the other remains unaffected.

Amensalism is an interaction in which the presence of one species has a negative effect on another, but the first species is unaffected. This could occur as simply as a human walking across a lawn, crushing the lowest level of the community.

Explain the importance of earthworm<br>

fredd [130]

<h3>Earthworms are extremely beneficial in agriculture. They aid in the following ways:</h3>

They help loosen up and aerate the soil as they burrow deep. This aids in the respiration of the roots of the plants, making them penetrate deeper and grow well

They are being used presently in vermiculture to produce high-quality manure

They are also used as baits to catch fish

They keep interchanging the topsoil with the layer just below, thereby increasing soil fertility.

The excreta of earthworms is rich in the nitrogenous matter and is required for plant growth

The type of cellular nuclear division that produces two cells with the same number and type of chromosomes as the original cell:

Helen [10]

This is Mitosis, which occurs with all nucleated somatic (body) cells, but not in germ (sex) cells.
Germ cells, aka gametes, on the other hand, undergo Meiosis, a process of nuclear cell division whereby 1 parent cell gives rise to 4 daughter cells. These daughter gametes, either sperm or egg cells, all have 1/2 the number of chromosomes as the original parent, termed "haploid." The genes of these gametes were also randomly assorted and crossed-over, allowing a shuffling of their chromosomes' genes.

What is the difference between inductive and deductive reasoning?

murzikaleks [220]

The main difference between inductive and deductive reasoning is that when we're doing inductive reasoning we're trying to create formal rules or formal inferences from a limited set of information, while during deductive reasoning, we're trying to deduce what would happen in a certain case based on general information available.

one hypothesis in the barn-swallow study was that long-tailed swallows would produce more offspring than average-tailed swallows

AURORKA [14]

I think the correct answer from the choices listed above is the last option. The control group to be used to test the hypothesis would be the swallows with average-length tails. A control group <span>is defined as the </span>group<span> in an experiment or study that does not receive treatment by the researchers.</span>
