Answer:
diversity of species increases the ability of ecosystems to do things like hold soils together, maintain soil fertility, deliver clean water to streams and rivers, cycle nutrients, pollinate plants (including crops), and buffer against pests and diseases—these are sometimes called 'ecosystem functions' or 'ecosystem.
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between
species, and of ecosystems.
explanation:
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention
Answer:
601 gram
Explanation:
1st we should know how may moles are there in 1.34 X 10 25 atoms
# moles of Al = # of atoms / # of Avogadro's num
= 1.34 X 10 25/ 6.12X10 23 =
= 22.26 mol of AL
so mass of AL = moles x m.wt
=22.26 x 26.98 = 600.55 = 601 gram
DONE
