What is ecology?

Back

Ecology is the branch of biology that studies the interactions between organisms and their environment, including the relationships among organisms and the relationships between organisms and their physical surroundings.

What is a limiting factor in ecology?

Back

A limiting factor is a resource or condition that limits the growth, abundance, or distribution of an organism or a population of organisms.

What is competition in ecological terms?

Back

Competition is the interaction between organisms or species in which both the organisms or species are harmed as they compete for limited resources such as food, water, or territory.

What are density-dependent factors?

Back

Density-dependent factors are environmental factors whose effects on a population vary with population density, such as competition, predation, and disease.

Front

What are density-independent factors?

Back

Density-independent factors are environmental factors that affect populations regardless of their density, such as natural disasters, climate, and human activities.

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic diversity, and ecosystem diversity.

Front

What is habitat fragmentation?

Back

Habitat fragmentation is the process by which large, continuous habitats are divided into smaller, isolated patches, often due to human activities like urban development and agriculture.

Front

What is an invasive species?

Back

An invasive species is a non-native species that spreads widely in a new habitat, often causing harm to native species and ecosystems.

What is the relationship between birth rate and population growth?

Back

When the birth rate is higher than the death rate, the population increases.

What is the impact of climate change on biodiversity?

Back

Climate change can alter habitats and ecosystems, leading to shifts in species distributions, changes in migration patterns, and increased extinction rates.
