The sampling technique which employs recording all the organisms within a specified square area is called "blank" the technique. a) transect b) area c) quadrat large industrial use of wind energy: is practical anywhere there is wind is restricted to localized areas of consistent wind cannot be developed anywhere natural catastrophes can upset the balance of an ecosystem. true false what is true concerning an ecological community? it is a large region of multiple organisms the boundaries, large or small, of a single organism the ecosystem of multiple organisms, regardless of a real extent

1. C). Quadrat

2. Cannot be developed anywhere.

3. True

4. The ecosystem of multiple organisms, regardless of a real extent.

Explanation:

1. A quadrat sampling is a technique that is used in ecology experiments. It utilizes a large square instrument of a particular dimension which allows the quantitative estimation of distribution and sample collection of plants or other creatures in an area covered within a square quadrat.

2. Wind energy is harnessed by the high speed wind currents. These wind currents causes the movement of the wind turbine that converts the wind energy into electrical energy. For commercial basis the wind energy cannot be develop from anywhere instead an area which receives high wind speed is useful for generation of wind energy for industrial use.

3. Natural catastrophes are the events that are hazardous and can cause major disturbance in a region. In an ecosystem the natural catastrophes can cause the loss of species. Hence, it will reduce the biodiversity of an ecosystem.

4. An ecological community is a community of multiple organisms which are the part of the ecosystem. Irrespective of the extent where the ecosystem lies in a region. The organisms interact among themselves and with their non-living environment in an ecological community.
