The sexual or asexual process by which organisms generate new individuals of the same kind; procreation.
Is a biological principle that follows a format in which a population of life forms grows at a faster rate when the population is larger.
Occurs when the growth rate decreases as the population reaches carrying capacity. Carrying capacity is the maximum number of individuals in a population that the environment can support.
A nerve cell that conducts impulses from a sense organ to the central nervous system.
Pertains to the number of a species that an environment can sustain, considering the limiting factors at play (e.g. food, water, competition, etc.). ... Accordingly, the carrying capacity is the population size at which the population growth rate equals zero.
Organisms that depend only on green plants or plant produce for their nutrition. For Example: Cow, goat, rabbit, etc.
Is the balanced state of having adequate biological defenses to fight infection, disease, or other unwanted biological invasion, while having adequate tolerance to avoid allergy, and autoimmune diseases.
The sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off.
Is an interaction between organisms or species in which both the species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor.

The loss or removal of nitrogen or nitrogen compounds; specifically : reduction of nitrates or nitrites commonly by bacteria (as in soil) that usually results in the escape of nitrogen into the air.
The conversion of atmospheric nitrogen into a combined form (as ammonia) through chemical and especially biological action (as that of soil rhizobia)
The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
Resources are environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem.
Any factor limiting the size of a population whose effect is dependent on the number of individuals in the population. For example, disease will have a greater effect in limiting the growth of a large population, since overcrowding facilitates its spread.
Is an organism that eats another organism.
