Sometimes called mechanical weathering, physical weathering is the process that breaks rocks apart without changing their chemical composition. These examples illustrate physical weathering:
Swiftly moving water
The answer would be true!
This question doesn't make since. it could mean its death rate is lower than its birth rate or it could mean just expansion
Explanation:
Metabolites are the different kinds of the substances which are essential to metabolism of the organism.
Metabolites produced by the plants can be categorized into the primary metabolites and the secondary metabolites.
The primary metabolites have important role in survival of plant and play an active role in the respiration and the photosynthesis.
On the other hand, the secondary metabolites are not involved in normal growth and the development of plant. Although absence of these type of metabolites can lead to impairment of survivability of plant in long run.
<u>Secondary metabolites are produced mostly by the plants for the defense purposes.</u> They include steroids, alkaloids, phenolics, essential oils, resins, tannins, lignins, flavonoids, etc.
