Answer:
1: Organisms that make energy are called producers.
Producers are the autotrophic or chemotrophic organisms which are capable of synthesizing their food either by photosynthesis or by chemosynthesis. In the process of photosynthesis organisms use sunlight as a source of energy to convert water and carbon dioxide into carbohydrates and oxygen. Also some simple organisms use chemical energy obtained by chemical inorganic substances and convert them as organic chemical substances to obtain them as food.
2: A decomposer recycles matter back into the food web and biogeochemical cycles.
A decomposer is an organic which feed upon dead decaying organic matter generated after the death of plants and animals. This process results in the simplification of organic matter into simpler substances which are again absorbed by the plants through soil.
3. The sun is the source of energy. The light energy from sun is converted into chemical energy in the form of food by the producers like plants.
4. The autotrophs are found at the base of a food pyramid.
The autotrophs are called as producers because they are capable of synthesizing their own food by the process of photosynthesis . The diversity of producers in nature is more as compared to other organisms therefore, it lies at the base of the food chain.
Explanation:
Dominant alleles are the alleles that show that show the physical traits
Contractile vacuole is an organelle will be found in chlorella but not the paramecium.
The lowest metazoans, such as sponges and hydras, and freshwater protozoa have regulating organelles called contractile vacuoles that gather extra fluid from the protoplasm and occasionally release it into the surrounding media. Wastes containing nitrogen may also be excreted.
The contractile vacuole (CV) complex is an osmoregulatory organelle found in free-living amoebae and protozoa that regulates intracellular water balance by storing and excreting excess water, enabling cells to survive under hypotonic stress, like that found in pond water.
