Correct answer: B) They produce most of the food that the ecosystem relies on
Decomposers are the organisms that break down the dead and decayed plants and animals. They also help in the breakdown of waste of other organism.
They are found to be very important for the ecosystem, if they were not present in the ecosystem them plant would not be able to get essential nutrients which are necessary for their growth. Because it the decomposers who help in the recycling of carbon and the nitrogen cycle.
Decomposers break down the dead and decayed material into simpler organic matter into carbon dioxide and nutrients.
Example: bacteria, fungi
Photosynthesis breaks down glucose and release carbon dioxide
Explanation:
1.Structure of virus- Schleiden and Schwann could not explain the structure and functioning of virus cell. They said that the function of body is coordinated function of cell which is not true in the case of virus because it only starts it's functioning when hosted by bacterial, plant or animal cell.
2.Prokaryotic cells- The cell theory do not holds true in the case of Pk cells because they do not have any well defined nucleus.
3.Multinucleate condition- The cell theory says that each cell have A NUCLEUS, but there are certain cells like tapetal cells that are coenocytic.
4.Cells without nucleus- Acc to cell theory there should be a nucleus in every cell, but human RBCs, sieve tubes of angiosperm are some of the cells lacking nucleus.
Answer:
Hyaline cartilage
Explanation:
Endochondral ossification is the process where the bone develops by replacing hyaline cartilage, cartilage serves as a template to be completely replaced by new bone. All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through endochondral ossification.
During endochondral ossification, chondrocytes proliferate, undergo hypertrophy and die; the cartilage extracellular matrix they construct is then invaded by blood vessels, osteoclasts, bone marrow cells and osteoblasts, the last of which deposit bone on remnants of cartilage matrix.
