Answer:
Human actions affect ecosystems through exotic species introduction, disease transfer, land conversion, habitat loss, modification and fragmentation, resource exploitation etc. All of these actions reflect negatively on any given ecosystem.
Explanation:
Abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. All of which human actions affect.
Answer:
nothing
Explanation:
2.composite cone volcanoes
3.shield volcanoes
4.pyroclastic volcanoes
Answer:
Shield volcanoes.
Explanation:
Hawaiian volcanoes are the types of vulcanos known as shield vulcanos. Their shape is slightly dome, it is like an inverted shield. They are located in a big area and they don’t have explosive eruptions. This type of vulcanos is created when magma enters the fracture of the stone. One of the most famous volcanos of this type is Mauna Loa in Hawaii.
B. Group B only
C. Both group A and group B
D. Neither group A nor group B
Answer:
B. Group B only
Explanation:
Control group is a research group that does not receive the substance being tested in the experiment. In the case shown in the question above, the experiment sought to test the effectiveness of a specific fertilizer in the growth of bean plants. For that, plants received the fertilizer (which is the tested substance) while plants did not receive the fertilizer (received only water), in this case, the plants that received only water are the control group of this experiment.
Answer:
Baboons are some of the most identifiable of the monkey world. They have tufts of hair on either side of their faces and large, hairless bottoms that can turn red. These old-world monkeys also do not have prehensile tails like some other monkeys, which means they don't use their tail like a hand
The following is not part of the nitrogen cycle - bbreathing in nitrogen gas from the atmosphere.
The nitrogen cycle is one of the biogeochemical cycles which includes the conversion of nitrogen into multiple chemical forms as it transfers among the atmosphere, terrestrial, and marine ecosystems.
Thus, The following is not part of the nitrogen cycle - bbreathing in nitrogen gas from the atmosphere.

The scenario that is representative of how agricultural practices can affect the environment is increased oxygen levels in a pond due to fertilizer runoff. Therefore, option A is correct.
Agriculture has a significant impact on the environment, both favorably and unfavorably. It can cause deforestation, water pollution, soil erosion, and climate change. Moreover, it can aid with CO₂ reduction, air quality improvement, wildlife habitat creation, and food production.
Agriculture can have significant adverse consequences on the environment, such as soil, water, and air pollution, but it can also have beneficial effects, such as absorbing greenhouse gases in crops and soils or lowering flood risks by employing specialized agricultural methods.
Thus, the scenario that is representative of how agricultural practices can affect the environment is increased oxygen levels in a pond due to fertilizer runoff. Therefore, option A is correct.

Your question is incomplete, most probably the full question is this:
Which of the following scenarios is representative of how agricultural practices can affect the environment?
a. increased oxygen levels in a pond due to fertilizer runoff
b. sediment accumulation in a body of water near a farm
c. soil compaction caused by tillage
d. increased plant growth caused by the application of herbicides
Answer:
The correct answer to the question, 'which of the following scenarios is representative of how agricultural practice can affect the environment' is A. Option A is chosen because it is the only option that refer to another environment which is different from that of the farm. When fertilizers are washed to nearby ponds as a result of erosion, it causes a lot of negative changes in the pond. For instance, the chemicals in the fertilizer can be poisonous to some of the smaller organisms in the pond, this will result in the death of these organisms. Fertilizer run off can also cause excessive growth of plants such as algae in the pond. This may block out the light necessary for the survival of the organisms in the ponds and may also reduce the amount of oxygen available to the organisms living in the pond.
