Ecology and Biodiversity

On the basis of origin, resources are classified as biotic (living) and abiotic (non-living).

A biofilm is a structured community of microbial cells attached to a surface and encased in a self-produced matrix. Dental plaque is a classic example of a biofilm formed on teeth.

A biofilm is a complex community of microorganisms attached to a surface and embedded in a self-produced extracellular matrix. This structure protects the microbes from environmental stressors.

Community-based management empowers local stakeholders to manage their own resources. This bottom-up approach relies on local knowledge and direct participation.

A habitat is the specific natural environment where a particular species lives and finds the resources it needs to survive. Option A describes an ecosystem or community.

An ecosystem consists of a community of living organisms interacting with their physical environment. Option B describes a habitat.

Grasslands have fertile soil and flat terrain, making them highly suitable for agriculture, which is why much of the world's grassland has been converted to farmland.

Biotic resources are those obtained from the biosphere and have life, such as plants and animals. Rocks, minerals, and soils are abiotic (non-living) resources.

Identity is formed through the ongoing interaction between an individual and their social context across micro, meso, and macro levels.

Aquatic life zones are the aquatic equivalents of terrestrial biomes, categorized by physical and chemical factors like salinity, depth, and temperature.

Deep ecology is a philosophy that views humans as part of the environment rather than superior to it, emphasizing the intrinsic value of all living things and the need for harmony.

Biodiversity refers to the variety and variability of life on Earth, encompassing the different species of plants, animals, and microorganisms, their genes, and the ecosystems they form.

A population consists of all the members of a single species living in a specific area at the same time. Ducks on a lake represent a population of that species.

A population is defined as all the individuals of the same species living in a specific area.

Abiotic factors are the nonliving chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems, such as water, sunlight, and air.
