How does energy affect competition in a rainforest?
Answer:
Energy affects competition in the tropical rainforest due to the dense population of trees found in this region.
Trees are producers and they compete mainly for water, sunlight and nutrients. Sunlight provides the source of solar energy which is instrumental in its photosynthetic process.
The trees form canopies and create competition among the ones who have lower stems and branches while the ones with longer stems continue to grow taller due to the availability of sunlight.
Competition may also affect the organisms living in this region as they compete for food.
The bottom area of a pond or lake where very little sunlight reaches is the

please help Mark and Vikki live in two different areas of North America. The temperature in Mark’s town today is 30°F. The temperature in Vikki’s town is 82°F. In both towns, the relative humidity is 90%. Is the amount of water vapor in the air the same in Mark’s and Vikki’s towns? Explain your answer.
Answer:
I think that the amount of water vapor in the air will be different because in Mark's town, it is cold and water in the clouds might turn to ice and come down as snow. And in Vikki's town, it is very warm so the water vapor might come down as rain.

Answer:

It was Charles Darwin who called the birds seen on the Galapagos islands as the finches. These birds show a remarkable diversification in their beak based on their chief food.
What are Darwin's Finches?Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.
These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.
The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.

Which component of the earth’s atmosphere is decreased due to photosynthesis?
ozone

carbon dioxide
Answer:
Carbon Dioxide
Explanation:
Let's see the reaction of Photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Where carbon dioxide and water are reactants and glucose and oxygen are products which means CO₂ and H₂O are taken from the environment and glucose is supplied to plants while oxygen is supplied back to the environment.

Describe what would happen to the abiotic factors within the ecosystem if the bacteria were eradicated from the ecosystem.
Answer: If a abiotic factor was to be removed from the ecosystem it can affect the entire ecosystem and all of the organisms that live there
Explanation:
Abiotic means which does not have life for example air, water, soil. Absence of bacteria can influence the abiotic factors in adverse ways.
What are abiotic factors?Abiotic components plays a major role in ecosystem, while biotic components are dependent on abiotic factors for their survival.
Both abiotic and biotic factors are related to each other, if any of these factors changes, it will adversely affect the ecosystem.
For instance, if bacteria were eradicated from ecosystem, it will affect the functioning of abiotic components which can result in increased pH, decreased decomposition etc.
Thus, the abiotic factors will get affected adversely if bacteria were eradicated from the ecosystem.
