Answer:
Correct Answer: 1.( d )
Solution:
- (d) Detrivores, (e.g. earthworm) break down detritus into smaller particles. The species that invade a bare area in succession is called pioneer species. The products of ecosystem processes are termed as ecosystem services, e.g., healthy forest ecosystems purify air and water, mitigate droughts and floods etc. Natality refers to number of births during a given period in the population.
