The diagram below shows a food web in a woodland.

Biology
1 answer:
Vedmedyk [2.9K]3 years ago
8 0

Answer:

<em>The correct option is A.  X, because organism X has the same role as the grasshopper</em>

Explanation:

In a food chain or a food web, a primary producer can be described as an organism which feeds on producers. The producers, in this case, are the corn stalks. Grasshoppers are primary consumers in this food web because they feed on the corn stalks. X is also a primary producer, just like grasshopper, because it feeds on the corn stalks which are the producers. Hence, option A is correct.

Answer:

Tt and tt

Explanation:

To solve this just work backwards. The first box has Tt so one parent has to have T and the other t. Since the tall plant is on the top, it is T_ and t_. Next use the second box (tt). They are both t so the final answer is Tt x tt.

Organisms may play only one role in an ecosystem true or false
anyanavicka [17]
This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.

You want to test whether duration of light exposure affects fish reproduction. What would be your control group and experimental
Triss [41]

Answer and Explanation:

During an experiment, data from an experimental group are compared with the data of a control group. These two sets are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals. This variable keeps constant in the control group.

The experimental group is the one that receives the experimental procedure, with changes in the independent variable.  There can be several experimental groups.

In the control group, the variable measured keeps constant, not influencing the results. This isolates the effect of the independent variable on the experiment and helps to find alternative explanations to the different results.

In the exposed example:

  • Control group: Certain amounts of fishes exposed to a normal number of light hours per day. For example, if under natural conditions in its original environment the species is exposed to 12 hour light, then the control group should be exposed constantly to 12 hours light a day to maintain its normal reproductive levels.
  • Experimental group: Certain amounts of fishes, equal to the control group, exposed to a different number of light hours per day. For example, there might be 5 experimental groups: one of them exposed to 4 hours light, a second group exposed to 8 hours light, the third group exposed to 12 hours light (The same as the control group), the fourth group exposed to 16 hours light, and the fifth group exposed to 20 hours light.

Except for light, the rest of the variables should be the same for all the groups.

How does the respiratory system affect the cardiovascular system
Anit [1.1K]

Blood is the fuel that keeps you going! Oxygenated blood is brought to organs and tissues via the arteries, while veins bring deoxygenated blood back to the heart to be replenished. The point is, without the respiratory system your blood would be useless.

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
