The Organization of Life
An ecosystem is a system where a lot of living things exist. It also includes the
relationship that these living things have with each other and with the non-living factors
in their environment. Scientists have classified the non-living parts of an ecosystem as
abiotic, while the living things within an ecosystem are classified as
biotic.
Biotic factors (living things) are often referred to as organisms. No
organism lives alone. All organisms have relationships with other living
things. As well, they must also deal with the abiotic (non-living) factors
in their environment. For example a polar bear interacts with seals, fish and humans
(biotic factors), as well as ice, water, temperature changes (abiotic factors).
Ecologists organize the relationships among organisms and their environment to help
study the interactions. They do this by using terms to describe systems of living things,
starting with the individual living thing (an organism) and progressing to the largest
system, which includes every living thing on Earth (the biosphere).
TASK
1. In your notebook, explain the following terms in your own words. (organism,
population, community, ecosystem, biome, and biosphere) Use page 259 of your
text and the glossary to assist you. Be sure to title your work Science, subtitle
The Organization of Life and include the date. As well, underline the word you
are explaining, space between each explanation, watch spellings and be neat.
2. Complete the flow chart below that represents “The Organization of Life”
Instructions: Neatly colour the picture below that represents a typical
field ecosystem (use appropriate colours). Then, complete the chart below
identifying the abiotic and biotic factors within this ecosystem.
