Which of the following groups of organisms uses sunlight to convert carbon dioxide and water into sugar and oxygen?
a. producers
b. decomposers
c. carnivores
d. herbivores
The group of organisms which uses sunlight to convert carbon dioxide and water into sugar and oxygen are producers. Thus, the correct option is A.
What are Producers in the ecosystem?Producers are any kind of green plants present in the ecosystem. Green plants make their own food by using the sunlight (solar energy) and carbon dioxide gas from the atmosphere with the energy to make sugar. The plant uses this sugar (carbohydrate), also called as glucose to make many different products, such as wood, leaves, roots, and bark.
This process through which plants produce their food is called photosynthesis. Photosynthesis occurs only in the plants which have chlorophyll pigment (chloroplast).
Therefore, the correct option is A.

Part1: Compare the relative concentrations (amount of GtC) of at least six (6) components of the carbon cycle
(e.g. The ____ has less GtC carbon than the ______ .)
Part 2: Explain how the total amount of matter is conserved during the carbon cycle.
hint-the earth is a closed system
Answer:
Explanation:
PART 2 : The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle.
Because elements are neither created nor destroyed under normal circumstances, individual atoms that compose living organisms have long histories as they cycle through the biosphere. In this depiction, a carbon atom moves from coal buried beneath the Earth's surface to a power plant and into the atmosphere. It eventually dissolves in water and is taken up by an algal cell, where it is then consumed by a copepod.

There are approximately 259 hectares per square mile. How many deer could a square mile of forest of mature American chestnut trees support for a year if they were the only organism consuming their nuts?
Answer:
25 deers
Explanation:
According to studies conducted by wildlife experts, a single deer needs roughly 25 acres of land in order to survive comfortably. Therefore we first need to find out how many acres are in a hectare, which based on a quick search online we see that 25 acres equal 10.11 hectares which is what a single deer needs to survive. Now we divide the total amount of hectares by the hectares a single deer needs in order to find out how many deers can survive on this total amount of land.
259 / 10.11 = 25.618
Finally, we can see that the 259 hectares can maintain roughly 25 deers.

B) carrying capacity
C) biological feedback
D) biological diversity
Answer:
The answer is carrying capacity
Explanation:
Had a test
An environment can support only as many organisms as the available energy, minerals, and oxygen will allow. The term best described by Carrying capacity
Carrying Capacity
It is the average population density or population size of a species below which its number tend to increase and above which its number tend to decrease because of shortage of resources. The carrying capacity is different for each species in a habitat because of that species particular food, shelter, and social requirements.
