Which is one way that a short-term environmental change will most likely affect organisms within an ecosystem? O It will lead to larger populations.
O It will lead to speciation.
O It will lead to adaptation.
O It will lead to forced migration.

It will lead to forced migration.

Explanation:

Changes in ecosystems affect living organisms. An ecosystem is a self supporting unit in which there is an exchange of materials and energy between the living and non living parts. The living part of an ecosystem is called its biotic component. This includes the organisms that live within the ecosystem. The nonliving parts of the ecosystem such as topography, rainfall etc are called abiotic components of the ecosystem.

A short-term environmental change usually forces organism to leave an ecosystem in their quest for survival. For instance, when short term environmental changes such as a sudden drop in rainfall causes drought, organisms migrate in order to obtain food and water. This is a forced migration.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
