Looking at the model above, if the hawks are increased, what will happen to the
grass? Please explain your reasoning
If the hawks are increased in this model, the grass will increase in the food chain.
What is a Food chain?This is defined as the sequence of transfers of matter and energy in the form of food from one organism to another.
When hawks are increased, the primary consumers will decrease which are the ones who eat the grass. This will therefore lead to an increase in the grass population.

Dead zones are caused largely by the input of agricultural fertilizers that stimulate phytoplankton blooms, which die, and are subsequently consumed through bacterial decomposition. Decomposition consumes oxygen, leading to very low dissolved oxygen levels. Imagine you are a NOAA employee asked to investigate and potentially mitigate (reduce) damage as result of this pollution. Write a short essay explaining the situation to your boss, beginning with an explanation of the problem. Your essay should address the following questions; what are the environmental impacts will it cause, and what can be done to reduce the impact?

Under what conditions are resources such as
water, food, or sunlight likely to be limiting factors
Answer:
Under what conditions are resources such as water, food or sunlight likely to be limiting factors? When population size is decreasing.
Conditions under which resources such as water, food, or sunlight likely to be limiting factors are when population size is declining.
Why is sunlight very important to the ecosystem?The Sun is the main origin of energy for organisms and the ecosystems of which they are a part.
Producers such as flora, algae, and cyanobacteria use the energy from sun rays to make organic matter from carbon dioxide and water.
This shows the start of energy gush via almost all food webs.
Thus, restraining factors are when population size is declining.

An element has an atomic mass number of 16 and an atomic number of 7. what is the elements protons and neutrons?
Answer:
7 protons, 7 neutrons (READ EXPLANATION)
Explanation:
The atomic number represents how many protons are in an element. Generally speaking, elements have the same number of protons and neutrons. So, an element with the atomic number of 7 will have 7 protons and 7 neutrons.
However it is possible for an element to have a differing number of neutrons (an element will always have the same number of protons because that number is how the element is identified in the first place). Elements that have a number of neutrons that is not the same as the atomic number are called isotopes.

Can a renewable resource become a nonrenewable resource? If so, give an example. (1 point)
Yes, a renewable resource, such as natural gas, can get used up faster than humans extract it from the Earth.
Yes, sunlight is a renewable resource but only during the day. At night, solar power cannot be generated, so during that part of the day it is a nonrenewable resource.
Yes, a renewable resource, such as fish, could go extinct if humans consume them faster than they reproduce.
No, renewable resources can never become nonrenewable.
Answer:
If mismanaged, renewable resources will become non-renewable.
Explanation:
For example: Groundwater can be over-pumped. If you burn a tree (plant) and don't plant another one.
Yes, a renewable resource can become a non-renewable resource.
What is a renewable resource?
A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes.
What is a non-renewable resource?A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.
Renewable resources can become non-renewable resources if they are used up faster than they can be replenished. Water is a common example of a renewable resource. If the water is used in a huge and big amount by every people of the earth for unnecessary purposes, then day by day the stock of the water level below in the earth will decrease and gradually the water will turn into a non-renewable resource.

The flow of carbon and energy through a marine ecosystem is shown here. Analyze the movement of matter and energy in this
ecosystem. Assume that the zooplankton have 20 grams per square meter of carbon available to them. Which statements can reflect
the movement of energy and matter in this ecosystem? Select ALL that apply.
es
The top predator has less than 20 grams per square meter available to it.
The phytoplankton have more than 20 grams per square meter of carbon
availability.
The dissolved organic carbon (DOC) is contributed from multiple levels of
the food chain.
The loss of carbon due to respiration by the zooplankton is greater than 20
grams per square meter.
The zooplankton can increase its biomass and carbon availability by
harnessing energy directly from the sun.
