Answer:

1.Biology is the scientific study of life.

2.Levels of organization are structures in nature, usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level.

3.The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

4.They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves.

5.Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others.

6.They are the heart, brain, kidneys, liver, and lungs.

7.to provide cells with oxygen and nutrients and to remove toxic waste products such as carbon dioxide.

8.A population is a group of organisms belonging to the same species that live in the same area and interact with one another. A community is all of the populations of different species that live in the same area and interact with one another. A community is composed of all of the biotic factors of an area.

9.It provides habitat to wild plants and animals. It promotes various food chains and food webs. It controls essential ecological processes and promotes lives. Involved in the recycling of nutrients between biotic and abiotic components.

10.The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.
