Answer:
The main role of chloroplasts is to conduct photosynthesis.
They convert light energy into relatively stable chemical energy via the photosynthetic process.

Answer: 1) When phosphorous is not bound in rocks, it moves quickly through land food webs. Constant use of phosphate-rich fertilizers will help increase phosphorus availability to plants, thus ultimately helping our ecosystems.
3) Minimizing the use of ammonia-rich fertilizers on lawns would not add excess nitrogen to the nitrogen cycle. As a result, it would help decrease the pollution of food webs in the oceans, decrease soil acidity on land, and decrease the amount of greenhouse gases in the atmosphere
Explanation:
The nitrogen and phosphorus cycles both are biochemical cycles. The nitrogen cycle involves the process of uptake of nitrogen from the atmosphere by the soil bacteria which is then become available to the plants for plant growth, from plants it is transferred to the other organisms in different forms.
The phosphorus is found in the rocks and these rocks wither and the inorganic phosphorus become available to the ecosystems.
Option 1 is correct, this is because the phosphorus is available on earth in the inorganic form inside the rocks, the withering and erosion processes make the phosphorus available to the plants. Another source of phosphorus to plants is phosphorus rich fertilizers. Thus plants will absorb phosphorus and grow. These plants will be consumed by other organisms thus the ecosystem will remain healthy.
Option 3 is correct, this is because nitrogen rich fertilizers can cause eutrophication in water bodies, or can contaminate the water. It will decrease the pH of the soil due to the formation of nitric acid. Also the nitrogen dioxide is the greenhouse gas.
Science is based on formulation and testing based on observational evidence.
One example would be that the sleep schedule of animals might be thrown off. It would be dark the whole day, so the crepuscular (dawn/dusk) animals might be a bit confused, as would the nocturnal (night) animals. Would they stay awake all "day" and all night? What about the diurnal (day) animals? Would they just not come out all day long?
Answer:
The natural selection is a theory made by Charles Darwin where animals better adapted to their environment tend to survive and produce offspring. for example, there are about 50% of beetle that are green and 50% orange. If crows tend to eat green beetles more, there will be more orange beetle to produce offspring so there wood then be less green beetles to be eaten by crows.
An environment can change over time and this will cause for the animals living in the environment to adapt as well. These changes will occur when an animal with undesirable traits don't survive to reproduce. The offspring of individuals that do survive to reproduce will inherit their parent's desirable traits. Over many generations, the desirable traits will be seen in more-and sometimes all- of the individuals in the population
Explanation:
That is the natural selection told in my words, but please do your best to rewrite your own sentence/paragraph. Copying another's work is called plagiarism and any teacher can automatically give you a 0% for this.
Anyway, goodluck.
