Henry observed the aquatic life in the pond, but also the
trees, vegetation, and animal’s species on land. The diversity observed by
henry is ecological diversity. Ecological diversity is the variation in the
ecosystems found in a region or the variation in ecosystems over the whole
planet. Ecological diversity includes the variation in both terrestrial and
aquatic ecosystems.
Answer: They are all genetically tractable
Explanation:
Yeast, fruit flies, nematodes, mice or the small plant Arabidopsis have known genome i.e their entire genetic information is known to the scientific community, thus they are EASILY MODIFIED in genetic research.
Also, they are simple eukaryotes (having cells with defined nucleus) so they can explain the processes in the human eukaryotic cell during genetic research
Both reasons make them genetically tractable
Animals obtain nitrogen by eating plants
