Selective logging—the practice of removing one or two trees and leaving the rest intact—is often considered a sustainable alternative to clear-cutting, in which a large swath of forest is cut down, leaving little behind except wood debris and a denuded landscape.

Answer:

Explanation:

Clear cutting can be define as the removal of entire vegetation cover or large forests from a region. But in selective cutting some unwanted trees, bushes, shrubs are cut so as to increase the area for the growth of trees which are of value. Selective cutting is more sustainable than clear cutting because in clear cutting the chances of loss of diversity of plant species is more. Also some species native to a region may get extinct by clear cutting. Hence, selective cutting is more sustainable.

You conduct a mark-recapture survey of eastern fence lizards (Sceloporus undulates) in a 2-hectare plot in eastern Arizona. You
Ksenya-84 [330]

Answer:

Option C

Explanation:

Given -

Total number of initially marked lizards (M) = 250

Total number of recaptured lizards (C) = 75

Total number of recaptured marked lizards (R) = 24

As we know that -

\frac{M}{N} = \frac{R}{C}

We have to find "N" . "N" is the total population size of lizards in a 2-hectare plot in eastern Arizona.

Thus, on rearranging the above equation, we get -

N = \frac{M * C}{R}

Substituting the given values in above equation, we get -

N = \frac{250 * 75}{24} \\N = 781.25\\N = 781.3

Hence, option C is correct

What is the ultimate source of energy for most organisms and how is this energy captured so it is useful in a food chain??
Luba_88 [7]
The ultimate source of energy (for most ecosystems) is the sun<span>. The ultimate fate of energy in ecosystems is for it to be lost as heat. Energy and nutrients are passed from organism to organism through the food chain as one organism eats another.</span>

To known the population size per unit area we use population density. Or sometimes use it for volume. It is expressed in quantity or in the type.  Mostly used for the living organisms, specifically humans. It's unit is expressed in square kilometers or may say in square mile. It is used for country, city, town and another territory. The negative relationship is found to affect the population density. It depends on the reproduction and survival.
