Which of the following describes a general community of deer?
Answer options:
All of the deer, raccoon, trees, birds, rocks, sky, air, water in a particular area
All of the deer in the world
All of the deer in a particular area
All of the deer, raccoon, trees, birds, and ants in a particular area
Answer: All of the deer, raccoon, trees, birds, rocks, sky, air, water in a particular area
Explanation: Community, also called biological community, in biology, an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
An interacting group of the species is called a community. All of the deer, raccoon, trees, birds, sky, and water in a distinct area makes the community.
What is a community?A community is also called a biological community and consists of the interacting species or the organism that lives together by depending sometimes on each other and some abiotic factors.
In an ecosystem, the potential interacting species live together in a particular area and influences each other in a certain way by sharing the same environment will be called the ecological or the biological community.
In a deer community, the related organisms like a raccoon, birds, water, rock, air and deer live and interact together in a defined area.
Therefore, option A. all the deer, rocks, air, water, sky, birds and trees make the biological community.

Explain how natural forces and human effects affect the observed global temperature (black line) in graph 2. Is solar radiation a natural force or a human effect?
Answer: There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean and land surface to increase.

How does energy move in a healthy ecosystem from the sun to the plants and animals?
Answer:
First,the sun transferes heat to the plants,helping them grow.Animals such as deer who would eat grass,eat plants.
Explanation:
Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose.
What is energy transfer?
The sun is the principal energy source for practically all ecosystems on Earth. Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose. Primary producers are then consumed by primary consumers, who are in turn eaten by secondary consumers, and so on. The food chain provides the simplest visual representation of this energy transfer.
A new trophic level is represented by each link in the chain, and the arrows depict the flow of energy through the chain. The primary producer is always at the bottom of a food chain. Plants are the most important primary producers in terrestrial ecosystems, whereas phytoplankton is the main primary producer in marine ecosystems. In their respective habitats, each generates the majority of the nutrients and energy required to maintain the rest of the food chain.
Gross primary productivity is the collective term for all the biomass produced by primary producers. After the primary producer has utilized the energy required for respiration, what is left over is what is known as net primary productivity. This is the portion that can be ingested and passed up the food chain by the main consumers.
Therefore, the transfer of energy within the trophic levels results in energy transfer.

Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.
Answer:
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.
Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.
What are convection currents?Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.
Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.
