What does biological productivity mean in biology?

In ecology, biological productivity is the rate at which living organisms produce biomass. It is usually expressed in terms of mass of new biomass per unit of time, usually per square meter. A common unit for biological productivity is g C m−2 yr−1, which is the amount of carbon fixed by plants and other photosynthetic organisms per square meter per year. It is one of the most important determinants of the amount of food available to animals.

What is biological productivity mean?

Biological productivity is a measure of how much biological material is produced per unit area of land, and it’s often used as a proxy for biodiversity. Biological productivity is a measure of primary production—the production of new plant or animal growth. There are three major categories of biological productivity: vegetation productivity, soil productivity, and fisheries productivity.

What does biological productivity mean in ecology?

Biological productivity is the rate at which an organism produces new biomass. One way of calculating this is by using the rate at which an organism's energy is transferred to its environment. This is known as primary productivity. Primary productivity is often expressed in terms of energy per unit of area, making it a common metric used in ecology.

What does biotic productivity mean in ecology?

Biotic productivity is the production of living things. It includes all the net primary production, all plant and animal productivity, as well as the productivity of the microbial world. In ecology, it’s the total production of a community. Biotic productivity is also often used to describe net primary productivity, which is an estimate of the amount of energy that plants and other primary producers in an ecosystem use to grow.
