Which are consumers within a spruce-fir forest ecosystem? a. mushrooms b. red squirrels c. limber pine trees d. bristlecone pine trees which is a nonliving factor that defines a spruce-fir forest ecosystem? a. type of soil b. type of trees c. type of bacteria d. type of mammals which are decomposers within a spruce-fir forest ecosystem? a. mushrooms b. pine martins c. canada lynxes d. limber pine trees

A.Consumers: Red squirrels

            B. Non-living system: Type of soil

            C. Decomposers: Mushrooms

Explanation:

Consumers are the organisms that feed on producers for their energy needs. The producers make food by the help of the process known as photosynthesis.

here, the red squirrels are known as consumers. They are primary consumers that feed directly on the plants.

The ecosystem consists of both biotic factors and abiotic factors. The biotic factors are known to be the living components of the ecosystem and abiotic components are the non living part of the ecosystem. Example: Type of soil is a non living part of ecosystem.

The mushrooms are known to be decomposers because they feed on the dead and decaying organic matter of the plants and animals and helps in cleaning the ecosystem.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
