2. Where is chlorophyll present in plants?3. What foods do the decomposers get?4. Name one scavenger |
| Answer» <p>Chlorophyllmolecules are contained inside chloroplasts, which are the food producers of the cell found in all green parts of aplant. Inside the chloroplasts, we also find thylakoid membranes, which contain photosystems.</p> <p>Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.</p> <p>Ananimal that feeds on dead organisms, especiallyacarnivorous animal that eats dead animals rather than or in addition to hunting live prey. Vultures, hyenas, and wolves arescavengers</p> <p>the green leaves contains chloroplast that contain green pigment called chlorophyll</p> | |

Give an account of Earthworm with itphysiological process. |
| Answer» <p>Anearthwormis a tube-shaped, segmentedwormfound in the phylumAnnelida. Earthworms are commonly found living in soil, feeding on live and dead organic matter. An earthworm's digestive system runs through the length of its body. It conducts respiration through its skin. It has a double transport system composed ofcoelomic fluidthat moves within the fluid-filledcoelomand a simple, closed blood circulatory system. It has a central and a peripheral nervous system. The central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve cord running back along its length to motor neurons and sensory cells in each segment.</p> <p>Worms are annelids, from the Latin word anulus meaning "ring." Worms are made up of joined, ringed segments. An adult redworm has between 200 to 400 circular rings. Try thinking of the giant sequoia trees and their rings. The tree rings grow around each other while the worm rings are stacked end on end.</p><p>The cuticle is the worm's outermost body wall. Beneath the cuticle are:</p><p>the epidermis, which is like our skin,a layer of nerve tissue which performs like our sense of touch,circular and longitudinal muscles for locomotion.The epidermis contains many sensory cells that transmit information to the nerve tissue. Within the layer of nerve tissue are cells that forward sensory information to the worm's nerve cord and on to the cerebral ganglion, the worm's version of a brain.</p><p>Circular muscles create the worm's body rings. These muscles contract and expand, shortening and lengthening the worm's body. The longitudinal muscles run the length of the worm. Acting in concert these sets of muscles enable the worm to propel forward, backward and sideways. Moisture in their environment lubricates this locomotion.</p> | |

What will happen. If we breathe pure Oxygen? |
| Answer» <p>Ifyoubreatheair with a much higher than normal O2 concentration, theoxygenin the lungs overwhelms the blood's abilitytocarry it away. The result is that freeoxygenbindsto the surface proteins of the lungs, interferes with the operation of the central nervous system and also attacks the retina.</p> | |
| 3768. |
1. Why should we breathe only through our nose? |
| Answer» <p>Ans :- The lungs actually extract oxygen from the air during exhalation, in addition to inhalation. Because thenostrilsare smaller than the mouth, air exhaledthroughthenosecreates a back flow of air (and oxygen) into the lungs. Our nostrilsand sinuses filter and warm/cool air as it entersourbodies.</p> | |
| 3769. |
Why do we need to breathe out carbon dioxide? |
| Answer» <p>Our bodies need oxygen to function. After we take a breath, the lungs transfer oxygen to our blood to be transported all over our bodies to help our cells work. Think about it — when you are running, you breathe more heavily to get more oxygen. Oxygen helps our cells work harder by breaking down the nutrients we get from food like sugars. With sugars and oxygen, our cells can create the energy they need to function.</p><p>This process also produces carbon dioxide. The carbon dioxide produced is a waste product and needs to be removed. Just like oxygen, carbon dioxide is transferred to blood to be carried to the lungs, where it is removed and we breathe it out. This is important because if we couldn't remove carbon dioxide from our blood, it would take up all the carrying capacity of our blood and we wouldn't be able to get oxygen to the rest of our body. This is another reason you breathe heavier when exercising — you produce carbon dioxide faster and need to get it out of your body to make room for more oxygen.</p> | |

How do water scorpions breathe? |
| Answer» <p>Water scorpions, being air-breathinginsects, carry a bubble of air with them between their forewings and their abdomen. When the tip of the long tail breaks the surface, diffusion via the tail between the bubble and the surrounding air renews thewater scorpion'soxygen supply.</p><p>Please hit the like button if this helped you</p> <p>👍</p> | |

17. Why we are concentrating more on finding the alternate sources of energy?18. Biogas plant is considered as a boon for the farmers. Explain. |
| Answer» <p>1) Fossil fuels which are traditionally used by human beings everywhere as an energy sources are non-renewable sources of energy. These sources of energy are limited and will disappear after some time. They are being consumed at a large rate. Therefore, we should conserve the energy sources.</p><p>2) Biogas is considered to be a boon to the farmers because Farmers can produce clean domestic fuel from the wastes like animal dung, dry leaves, dry plants, etc. Biogas can be used to generate electricity which can be utilised to run modern machines used in the fields to save time and energy.</p> <p>thanks</p> | |
| 3784. |
. Make a list of as many energy sources as you can think of. |
| Answer» <p>Solar energy comes from the sun. Some people use solar panels on their homes to convert sunlight into electricity.Wind turbines, which look like giant windmills, generate electricity.Geothermal energy comes from the Earth's crust. Engineers extract steam or very hot water from the Earth's crust and use the steam to generate electricity.Biomass includes natural products such as wood, manure and corn. These materials are burned and used for heat.Dams and rivers generate hydropower. When water flows through a dam it activates a turbine, which runs an electric generator.</p> | |
