Newton's universal law of gravitation states that all objects attract each other with a force directly proportional to their masses and inversely proportional to the square of the distance between their centers. When considering objects on the surface of the Earth, the force is directly proportional to the product of the mass of the object and the acceleration due to gravity at the Earth's surface. Since the Earth is larger than any other object under consideration, the object is drawn toward the Earth.
Explanation:
The magnitude of the gravitational force between two objects is given by Newton's universal law of gravitation:
where
:
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
This force is always attractive.
At the Earth's surface, this can be rewritten as

with
where M is the mass of the Earth, R is its radius, and m the mass of the object.
g is called acceleration due to gravity and it is the value of the acceleration due to the force of gravity of any object near the Earth's surface (its value is approximately
. Since the Earth is much more massive than any other object, the object is attracted towards the Earth (so, it accelerates towards it); the Earth is also attracted by the object, however, being its mass so large, its acceleration is negligible.

Answer
C. Tagging and wildlife tracking
Explanation
Wildlife tracking is a process employed by biologists and scientific researchers including conversational agencies to remotely the movements and migratory patterns of free-ranging wild animals using GPS and other sensors. The tracking and monitoring of these endangered species is vital because it helps in the conservation process. Through the monitoring of wildlife, agencies can keep track of animal potters, population demographics and habitat utilization.
If one trophic levels population increases or decreases too much, it can decrease the amount of producers, this decreasing the amount of energy available in food web which can cause population crash.
According to the image, X is for attracting pollinators, Y is for the production of pollen, and Z is for the production of eggs
<h3>Parts and functions of flowers</h3>
The image shows the different parts of a typical flower.
X is a petal. Petals are usually colorful and serve to attract insect pollinators to flowers.
Y consists of the anther and the stigma. Both represent the male organ of the flower and produce the male gametes, otherwise known as pollens.
Z consists of the stigma, the style, and the ovary. They all represent the female reproductive organ of the flower. Pollen lands on the stigma, travels through the style, and reaches the ovary. The ovary houses the ovule or the eggs.
