The major difference between the flow of matter and of energy is that the flow of matter occurs in a cyclic manner i.e. it is recycled, however, the flow of energy in an ecosystem is unidirectional which means, it is not recycled. The flow of matter follows the following path
1) Decomposers release nutrients when they break down dead organisms
2) The nutrients are taken up by plants through their roots
3) The nutrients pass to primary consumers when they eat the plants
4) The nutrients pass to higher-level consumers when they eat lower-level consumers
5) When living things die, the cycle repeats
In case of flow of energy, the energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life. This loss of usable energy occurs because each energy transfer results in the dissipation of some energy into the environment as heat
Answer: They possess different functional groups.
Explanation:
Organic compounds are molecules composed of many carbon atoms bound together and in turn bound to hydrogen atoms. These molecules form the lipids, proteins, carbohydrates and nucleic acids that constitute all living beings. The reason why there is so much variety of organic molecules is because each one can have one or several <u>functional groups in different positions, which gives them unique properties.</u>
So a functional group is a group of atoms linked in a certain way, which present a specific physical-chemical structure and properties that characterise the organic compounds that contain them.
Examples are:
- Lipids: A carboxylic acid
- Proteins: A carboxyl group and an amino group
- Carbohydrates: An aldehyde or ketone group
- Nucleic acids, Nucleotides: A phosphate group
It is 2 actually because based on the cells present and the ECM structure, we differ two types of connective tissues
