Answer:
because existing cells divide to produce new cells
Answer:
The correct answer is - sun - producer - the consumer – decomposer.
Explanation:
Sun is the ultimate source of the energy on the earth and is responsible for all the energy that is present or moves between various organisms in an ecosystem.
Sun provides energy in the form of light energy which is converted by the producers by photosynthesis into food and when consumers eat producers for food and energy 10 percent of energy passes from the producers to the consumers and the rest 90% lost during life processes. At the end of the chain, decomposers get energy from the dead matter of the consumers.
Answer:
Blood vessel, a vessel in the human or animal body in which blood circulates. The vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles. Very small branches that collect the blood from the various organs and parts are called venules, and they unite to form veins, which return the blood to the heart. Capillaries are minute thin-walled vessels that connect the arterioles and venules; it is through the capillaries that nutrients and wastes are exchanged between the blood and body tissues.
Explanation:
Answer:
Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles
Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.
Ribosome: A small particle in the cell that can make proteins.
Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.
Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.
Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.
Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)
Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).
Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.
Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.
