a.Parasite because it is a living thing.
Biogeochemical processes found in prokaryotes:
- methanogenesis
- methane oxidation
- nitrification
- denitrification
- sulfur oxidation
- sulfate reduction
- nitrogen fixation
Biogeochemical process Found in eukaryotes and prokaryotes:
- respiration
- carbon fixation
- fermentation
Biogeochemical cycles mainly refer to the movement of nutrients and other elements between biotic and abiotic factors. The three types of biogeochemical cycles are hydrological cycle, sedimentary cycle and gaseous cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Solar energy.
This is because the solar energy arrives and is trapped as radiation and heat.
Some major causes as to why biodiversity occurs are the following...
habitat loss and fragmentation, over-exploitation for commercialization, invasive species, pollution, global climate change, illegal wildlife trade, and species extinction
