Lesson plans for Biology
Week 17, November 28-December 2, 2011
Unit 7: Speciation and Population Biology
Concept 4: Biological Evolution
Understand the scientific principles and processes involved in biological evolution.
Concept 5: Matter, Energy, and Organization in Living Systems (Including Human Systems) Understand the
organization of living systems, and the role of energy within those systems.
S4-C4-PO2. Explain how genotypic and phenotypic variation can result in adaptations that influence an
organism’s success in an environment.
S4-C4-PO3. Describe how the continuing operation of natural selection underlies a population’s ability to adapt
to changes in the environment and leads to biodiversity and the origin of new species.

Today’s vocabulary:
Plankton: tiny, free-floating organisms that occur in aquatic environments.
Phytoplankton: autotrophic component of the plankton community.
Zooplankton: tiny animals that form part of plankton.
Wetland: ecosystem where water either cover the soil oris present near the surface of the soil for at least part of the year.
Estuary:wetlands formed where rivers meet the ocean.
detritus:paticles of organic material that provide food for organisms at the base of the estuary’s food web.
Salt marsh: temperate zone estuary dominanted by salt tolerant grasses.
Mangrove swamp:coastal wetland dominated by mangroves.
Photic zone: zone where sunlight reaches and photosynthesis occurs.
Aphotic zone: zone where no sunlight reaches.
Zonation: prominent horizontal banding of organisms that live in a particular habitat. 42. Coastal ocean: marine zone that
extends from the low-tide mark to the continental shelf.
Kelp forest:coastal ocean community named for its dominant organism.
Coral reef: diverse and productive environment named for primary animals.
Benthos: organism that live on or near the ocean bottom.
