Eutrophication occurs due to the increased concentration of natural nutrients. Conversely, artificial eutrophication happens due to human activities.
<h3>Eutrophication and artificial eutrophication</h3>
Eutrophication is a biological phenomenon that occurs due to the increased concentration of natural nutrients such as algae in a water body.
Artificial eutrophication is a specific type of eutrophication process caused by human activities.
Artificial eutrophication can be caused, for example, for an excessive overload of fertilizers in a lake.

<u>Answer</u>:- Active transport
<u>Explanation</u>:-
There are two types of membrane transports
1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from <em>high concetration to low concentration.</em>
2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from <em>low concentration to high concentration.</em>
<em>The active transport is of two types:</em>
1. <em>Primary active transport-</em> in this type of transport <em>ATP</em> is used as an energy source to move the substances against the concentration gradient.
2.<em>Secondary active transport</em> - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.
- The membrane proteins that are associated with active transport are called as <em>carrier proteins</em>. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.
So, the <em>active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.</em>
Sorry i needed the points... good luck tho
Answer:
An electromagnetic wave
Explanation:
An electromagnetic wave is a transverse wave that can travel across space as well as through matter. When it travels through space, it doesn't lose energy to a medium as a mechanical wave does.
It reveals that they have relationships of being friends.
