<h3>prey and its food source</h3>
The presence of a top predator also helps to maintain balance in an ecosystem by influencing the behaviour and movements of its prey through the fear of being caught.
<h3>What is Trophic Cascade ?</h3>
trophic cascade, an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain
- When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it.
- The results of these trophic cascades can lead to an ecosystem being completely transformed.

I believe that one water molecule of water is attracted to another because of its polarity.
Humans do have 5 sensory organs namely eyes ears nose tongue and skin. Each of them do have different stimuli to receive from environment.
<h3><u>Explanation:</u></h3>
Most of the sensory organs house in the head of human beings. Functions of each of them are discussed below:
A. The eyes house in the cranium orbit and are two in number which senses the visible spectrum of electromagnetic waves also called as light rays. The retina in the eyes sense it and sends the information via the optic nerve.
B. The ears house on lateral sides of head which sense the audible range sound waves. The organ of Corti senses the sound vibrations and sends them to brain via auditory nerve.
C. The nose house on the midline of head on the anterior surface which senses the smell and sends via nerves.
D. Tongue houses in the buccal cavity which senses the taste of food and sends via different nerves to brain.
E. Skin is located all over the body and it senses different stimuli like pressure, temperature, pain etc and sends to brain via different sensory nerves.
Answer:
top picture is a Eukaryotes, Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
bottom picture is a prokaryote. A prokaryote is a typically unicellular organism that lacks a nuclear membrane-enclosed nucleus.
