Here is an explanation sorry if it’s long :/
Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. They are used in every process of an organism’s body. Some of the processes are growth (building cells), repair (healing a wound), and maintaining life (breathing).
Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.
From these basic nutrients, plants and other autotrophs synthesize, or create, their own nutrients, such as sugars. The human body can also synthesize some nutrients, such as amino acids. However, most organisms need nutrients created by autotrophs. People and animals get most of their nutrients from food.
Essential nutrients are nutrients that the human body is unable to synthesize. They must be obtained from food or water. Essential nutrients include carbohydrates, proteins, fats, vitamins, and minerals.
In the deep waters of the ocean, coral reefs are found in abundance. Algae live on these coral reefs, providing nutrition and producing pigments that give color to the corals. The corals offer shelter to the algae. So, they share a association. Climate change has led to increased temperatures and has caused the corals to throw away the algae living inside them. This action causes the corals to be bleached because of a lack of pigment. This change will lead to a decrease in the coral growth, reduced fecundity and can cause death of corals.

Explanation:
A natural blind spot also called the optic disc in the eyes occurs where the blood vessels and axons of the ganglion cells leave to form the optic nerve. it is so called because there are no receptors (rods and cones) in this part of the retina. Artificial blind spots can also be formed when something prevents light from getting to the photoreceptors which are the rods and the cones.
