CANGSS: MS-LS 2 -1. Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem. �Unit 4: Interactions in Ecosystems �Module 2: �Lesson 1: Resources in Ecosystems.

Objective (s)/ I can: � • Relate how resource availability affects the growth of organisms and populations.

How can a population grow or get smaller? �Population- is a group of organisms of one species that live in the same area at the same time. �What can cause the population to change?

Population Size �New individuals are added to the �population it grows. �Individuals are removed from � population gets smaller. �Population stays the same size �Individuals added = Individual removed

Explore: Activity Tasks Option A 1. Describe your observation for each image. Option B 1. Think and describe a situation of how abundant 2. Write the label resources affect that best matches the growth of an what is happening individual. in each image Explain: Option C 1. Compare the effects of abundant and shortage of resources on the growth of individuals and populations respectively in different regions in UAE. How resource availability can affect the growth of individuals and populations.

Elaborate: �Extended thinking: Integration with Microbiology �Why in the case of water shortage, drought season, the plant wither and loses its normal shape? Explain this phenomenon starting from the cellular level. �Answer: Without water, the vacuole will not be able to exert pressure against the other cellular structures, the walls of the cell, as a result the cells collapses inward. Because this is happening in each cell, the entire plant loses its normal shape.
