Use examples to explain how changes to both living and non living parts of an ecosystem can affect individuals and populations.

Living Things in an Ecosystem Example - In a pond, for example, living organisms range in size from the algae and zooplankton in a drop of pond water to the larger fish, amphibians, lilies and cattails that make their homes in the pond. All the different populations of species co-existing and thriving within that same environment define the inhabitants of an ecosystem. The resilience of the community hinges on a cycle -- or chain of events and processes -- that creates food and energy for all the organisms within the community.

Non Living - The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks,water,soil,light,rocks etc.

Explanation:

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
