Answer:
The first trophic level
Explanation:
The most important trophic level in the ecosystem is the the first trophic level. This trophic level is dominated by the plants the furnishes the ecosystem with food.
- The ecosystem is made up of living and non - living components.
- To being with, the trophic levels are the feeding levels which corresponds with the energy levels.
- Now, the most important of all is the first trophic level
- It is made up of plants which are called producers.
- They use inorganic matter to produce food for the whole ecosystem.
- This food is the source of energy for all living activities in the system.
Answer:
Plants and animals both are living organisms that are directly dependent on the air. The air is comprised of various gases with definite proportions such as 78% of nitrogen, 21% of O₂, 0.9% of argon, 0.03% of CO₂, and other minor gases.
Oxygen (O₂) is the main gas that is essential for life to exist. Without this gas, no organisms can survive.
The organisms inhale oxygen (O₂) gas and exhale carbon dioxide (CO₂) gas.
These gases play an important role in the lives of plants and animals as it helps in carrying out the process of respiration. This process is essential in order to generate energy in the body of the organisms where the food particles (commonly known as sugar) are disintegrated by the cells. This is how an organism respire by inhaling O₂ gas and exhaling CO₂ gas.
Robert hooke coined the term cell when studying thin slices of cork. these Dead
Plant Cells were the first cells observed because the thick cells.
DNA fragments are cut out restriction enzymes (restriction endonucleases) and then joined together using enzymes called DNA ligases.
<span>Restriction enzymes are enzymes which recognize target sequences (recognition sites) and cuts DNA at or near those sequences.</span>
DNA ligase is an enzyme that connects the gap between the molecules (if they have matching ends).
