Crowding and food quality are two environmental issues of restaurants.

Environmental issues are defined as harmful effects to Earth and its natural systems due to the actions of humans.

The food supply chain and restaurant customer experience generate a lot of waste – from food waste to plastic waste, and more. Unfortunately, one-third of the world's food gets wasted. This waste alone amounts to 8% of the world's greenhouse gas emissions.

Hence, option B is correct.

Explanation:

In photosynthesis, the transformation process is in which the light energy is converted into chemical energy. Therefore, option (D) is correct.

Photosynthesis can be defined as a process by which phototrophs transform sunlight into chemical energy. This chemical energy can be stored in the form of sugars such as glucose, which are formed from water and CO₂ gas.

In the Photosynthesis process, the components are carbon dioxide and water which yield products oxygen gas, and glucose. Therefore, the photosynthesis reaction is generally said to be an endothermic reaction because the energy is provided in the form of sunlight.

[tex]6CO_2 +6H_2O\longrightarrow C_6H_{12}O_6 +6O_2[/tex]

Each chloroplast in green plants contains a green-colored pigment called chlorophyll which is mandatory for this process to occur. Sunlight is absorbed by the chlorophyll of the plants whereas carbon dioxide gas and oxygen gas enter via the tiny pores of the stomata of leaves.

The equation for luminous flame assuming the laboratory gas is butane is fuel + oxygen → [tex]CO_{2} + H_{2}O[/tex].

Natural gas, the source of butane, would be a colorless, odorless, but also shapeless gas by nature. This kind of gas is extremely prevalent throughout the world and seems to be comparatively cheap to mine as well as produce.

A burning flame that is clearly seen would be called a luminous flame.

When fuel is reacted with oxygen gas then it will form carbon dioxide and water. It can be written as:

fuel + oxygen → [tex]CO_{2} + H_{2}O[/tex].

A conservation scientist is one who manage improve, and protect natural resources to maximize their use without damaging the environment. The correct option is C.

A scientist is defined as a person who always studies systematically and uses research and evidence to prepare hypotheses. A conservation scientist is the person who protects, manages and improves the natural resources.

It is the conservation scientist who supervise the forest and give instructions to the workers and technicians who do the labour work for maintaining the forest. They also analyze the data on forest and soil quality and notice any damage to trees caused by fires.

The conservation scientist is also involved in choosing and preparing sites to plant new trees and it is their duty to remove the timber with minimum environmental damage. They also participate in the suppression of the forest fire.

Thus the correct option is C.

• Temperature measurements

Temperature testing aids in determining the pace of biochemical reactions in an aquatic environment, as well as whether they can occur at all. If the water temperature is too high, the water's ability to contain oxygen is reduced, and organisms' ability to withstand certain contaminants is reduced.

• Checking the pH level

This instrument determines the acidity of water. The majority of aquatic species can only thrive in a pH range of 6 to 8.

• Test for chloride

Chloride may be found in both fresh and salt water. Mineral dissolution and industrial pollutants, on the other hand, can worsen its levels.

•  Testing for salinity

The total amount of non-carbonate salts dissolved in water is calculated. The salinity of your groundwater can tell you how salty your topsoil will become as the water table rises.

• Oxygen Dissolved Test

The amount of oxygen dissolved in water is measured with this device. Aquatic life can't conduct cellular respiration without it, hence it's an important indication of water quality.

•  Test for turbidity

Measures the quantity of suspended particle matter in the water, or, to put it another way, how clear the water is. When there is a lot of turbidity in the water, photosynthesis suffers because light can't get through, which raises the water temperature.
