Identify three nonliving parts of an ecosystem. Then explain how the nonliving parts impact the different kinds of organisms that live in the ecosystem and the population size of these organisms.
(2 points)
Pg 127-The non-living parts are air, water, soil, temperature and sunlight. Without water everything would die. The air contains oxygen that all plants need. Temperature must be able to support life, by organisma adapting. Plants need soil. All life needs energy from the sun.
