Biology Content Targets (2011-2012)

Target Set 1

– Ecology

I can apply all lab/activity concepts, skills, and results from this unit as specific support of the targets listed below.

I can integrate two or more targets together into one cohesive idea or explanation.

I can use the BioThemes to connect unit content in a detailed and reflective manner, citing specific examples from the unit.

1.1

I can distinguish between the

biotic

and

abiotic

components of an ecosystem.

1.2

I can provide specific examples of a

population

,

community

and

ecosystem

, and distinguish between these levels of organization.

1.3

I can define

symbiosis

and distinguish between the three types of relationships in a community:

commensalism

,

parasitism

, and

mutualism

, providing an example of each.

1.4

1.5

1.6

1.7

I can describe and provide examples of

I can describe and provide examples of

I can distinguish between

habitat

and

producer/consumer predator/prey niche

.

ecological relationships.

ecological relationships.

I can explain the

competitive exclusion principle

, which states that no two species can inhabit the same niche so they must adapt, migrate, or become extinct.

1.8

I can predict how changes in one population might affect other populations based upon their relationships in a

food web

.

1.9

I can use a food web to identify and distinguish between

producers (autotrophs), consumers (heterotrophs),

and

decomposers

.

1.10

I can explain and diagram the flow of energy through

trophic levels

of a food web (i.e.

ecological pyramids

:

energy pyramid

,

pyramid of numbers

, and

pyramid of biomass

).

1.11

I can describe energy flow through an ecosystem, accounting for energy dissipated to the environment as heat.

1.12

I can describe the role of

decomposers

in the flow of energy and transfer of matter in an ecosystem.

1.13

I can analyze and explain

biodiversity

issues and the causes and effects of

extinction

(local, ecological,

and

biological)

.

Local: disappearance from a previous location, ie. Deerfield

Ecological: not enough left to fulfill role in ecosystem

Biological: completely gone from Earth

1.14

I can recognize that, and describe how, human activities can deliberately or inadvertently alter the equilibrium in ecosystems.

Examples include introduction of

invasive species

, development of natural lands,

edge effect

resulting from suburban sprawl, etc

1.15

Humans also may have positive effects on ecosystems.

I can explain the influences that affect population dynamics, such as

competition

,

limiting factors

,

birth/death rate

, and

immigration/emigration

.

1.16

I can illustrate and interpret the features of the following population growth curves:

exponential growth - J curve

,

logistic growth - S curve

(including

carrying capacity

and

population crash

), and

predator/prey.

1.17

I can explain how biotic and abiotic factors

cycle

in an ecosystem (water, carbon/oxygen, and nitrogen), and describe the role of cycles in transferring matter crucial for sustaining life.

----------------------------------------------------------------------------------------------------------------------------

ENRICHMENT:

I can describe ecosystem stability, including stages of succession (

primary succession

and

secondary succession

).

I can describe the

greenhouse effect

and

global warming

and list the possible causes of each.

Idea for Future:

PROJECT: Human Impact on Ecosystems (negative and positive)

; present in a poster session

-Invasive Species, asian carp or others

-Global Climate Change

-Oil Drilling in ANWR

-Coal Burning Power Plants, air and water pollution issues

-Species Extinction, locally and globally

-Biomagnification, mercury contamination and pesticides, hormones in our foods
