Ecology and Population Dynamics

Front

What is Ecology?

Back

Ecology is the branch of biology that studies the interactions between organisms and their environment, including both biotic (living) and abiotic (non-living) factors.

Define Population Dynamics.

Back

Population dynamics refers to the study of how and why populations change in size, density, and structure over time, influenced by factors such as birth rates, death rates, immigration, and emigration.

What is Carrying Capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can sustainably support without degrading the habitat.

Front

What are Biotic Factors?

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms, that affect the population and community structure.

Front

What are Abiotic Factors?

Back

Abiotic factors are the non-living physical and chemical elements in an ecosystem, such as temperature, water, soil, and sunlight.

Front

What is a Biome?

Back

A biome is a large geographical biotic unit, a major community of plants and animals with similar life forms and environmental conditions, such as a tropical rainforest or desert.

Front

What is Competition in Ecology?

Back

Competition is the interaction between organisms or species in which both are harmed as they vie for the same resources, such as food, space, or mates.

Front

What is a Density-Dependent Limiting Factor?

Back

Density-dependent limiting factors are factors whose effects on the size or growth of a population vary with the population density, such as food availability, disease, and predation.

Front

What is a Density-Independent Limiting Factor?

Back

Density-independent limiting factors are factors that affect population size regardless of the population's density, such as natural disasters, climate changes, and human activities.

Front

What is the difference between Immigration and Emigration?

Back

Immigration is the movement of individuals into a population from other areas, while emigration is the movement of individuals out of a population to other areas.
