Homework:

-Unit 6 (Ecology), the assignment is Unit 6.4.

Synthesis Question 4 (This is your assignment; do this prior to returning to class; it will be handwritten):

Class, answer the following question (in less three sentences or less) and allowing a minute (sixty seconds) to read, without use of notes, and brainstorm. Then allow four minutes to write concisely to answer.

All species on Earth interact with one or more other species within that same environment. These interactions affect the amount of energy that each organism/species can save and put toward reproduction. Some interactions drain energy away and thereby reduce reproduction; while yet other interactions allow for the gaining of energy for increased reproduction. In no more than three sentences, describe 3 interspecific Interactions among species and state how reproductive energy is affected for each species in the relationship.
