Answer:
The reason that there is no fruit even the plant produced healthy flowers maybe because
1. absences of pollinators due to declining poliinator population
2.weather conditions are preventing pollination
3. prevalence of flooding
Explanation:
1.Fruits are direct result of pollination. Due to the decrease in the number of pollinators especially orchid bees, some fruit bearing plants produce flowers but no fruit.
Bees decline their population because of parasites, diseases, exposure to chemicals and other environmental factors.
2.Unfavorable factors may prevent the agents of pollination to do their jobs. Bees and other insects may be hindered by wet or cold weather or some use of chemicals.
3.Brazil nut grow in lowland rainforest where there is no flooding.

Answer:
<em>The correct option is A. The Population will decline over time</em>
Explanation:
As the phytoplanktons won't receive enough sunlight, they will not be able to make enough food by photosynthesis. As a result, the phytoplanktons will start to die and they won't be able to reproduce abundantly like before. Hence, the population will decline.
Other options like option B are false because the population will not decrease their need for food. They will start to die due to lack of food and sunlight.
Answer:
Identifying elements in astronomical objects using their spectra. Measuring the spectrum of light from a star can tell astronomers what the star is made up of. Since each element emits or absorbs light only at a particular wavelength astronomers can identify what element are in the stars from the lines in their spectra.
