Primary producers are the original source of food in the vent ecosystem, using chemical energy to create organic molecules. All other life depends on primary producers, and they have the greatest biomass in the community.
Primary consumers get their energy directly from the primary producers by eating or living symbiotically with them.
First order carnivores prey on the primary consumers and in turn are eaten by other animals.
Top order carnivores eat other consumers and carnivores but are rarely hunted by other creatures. Because they are separated from the primary food production by several layers, top order carnivores have the smallest biomass in the food web.
According to standard first aid procedures, severe external hemorrhage is best controlled by applying direct pressure.
Standard first aid procedures follows the acronym DRABC. These acronyms describe the procedures to be used when providing the first aid. Here, D stands for Danger (assess the danger), R is response (check for consciousness), A is Airway (open airway), B is Breathing (check for breathing )and C is Circulation (chest compressions).
Hemorrhage is the excessive bleeding from a part of the body due to highly ruptures blood vessel. It can occur both inside as well as outside the body. If hemorrhage inside the body is not stopped it can cause clot formation, that will hamper the working of nearby cells and tissues.

C. F1 generation is all Yy (let Y be yellow and y be green). Y is dominant to y. The F2 could be YY, Yy, Yy, or yy. 3:1
100% would be red because if you take your chart, you would put Rw and Rw on the columns. which would lead to all 4 boxes being, Rw, Rw, Rw, Rw.
Answer:
B. Carbon dioxide
Explanation:
First of all, let’s write out the photosynthesis equation to identify the products and reactants.
6CO2 + 6H2O + energy —> C6H12O6 + 6H2O
In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.
In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.
Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.
We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.
Therefore, the best answer choice is B. Carbon dioxide
