Chapter 52: An Introduction to Ecology
and the Biosphere
Objectives:
-Understand that ecology integrates all areas of
biology
-Understand interactions between organisms
and the environment limit distribution of species
-Aquatic biomes are dynamic ecosystems that
cover most of the earth
-Understand that climate determines the
distribution and structure of terrestrial biomes.
Organismal Ecology
-Physiology and evolutionary ecology
Global Ecology
-Energy flow within the Biosphere
Community Ecology
-Interactions between species in an
ecosystem.
Landscape Ecology
-Connectedness of various ecosystems
Population Ecology
-Population dynamics
(change over time)
Ecosystems
Ecology
-Energy flow within an
ecosystem
Why do organisms live where they do?
-Biotic Factors
-Behavior
-Habitats
-Relationships with other organisms
Abiotic Factors
-Climate (Macro and Mirco
-Chemical
-Physical
Kangaroos live in the wettest of
areas and in the driest climates
that are susceptible to drought.
A Closer Look at Climate: Why
are Ecosystems where they are?
3. Mountains
1. Water
4. Air Circulation and Wind Patterns
2. Latitude and Seasons
Aquatic Biomes
-Two types: Marine and
Freshwater
-Largest part of the Biosphere
-Know the various zones
-Aquatic Ecosystems have
variations in temperature
(Stratified)
Freshwater Ecosystems
Shallow, nutrient rich,
oxygen poor
-Lakes
-Streams/Rivers (Moving water)
-Estuaries –Freshwater flows into salt
water
-Wetlands
Fresh water has two zones
1.
Littoral = Well lit and rooted plants
2.
Limnetic Zone = Well lit, phytoplankton
Deep, nutrient
poor, oxygen rich
Intertidal zone is where land meets
water and periodically submerged.
Oceanic Pelagic Zone is the vast
ocean blue
Marine Ecosystems
Benthic Zone is the bottom
of the ocean – include
hydrothermal vents
Coral Reefs – Calcium Carbonate
(High Oxygen)
Terrestrial Ecosystems
-Based on Temperature and
Precipitation
-Latitude = Climate
-Altitude, Soil, and Water also
determine ecosystems
*Know general characteristics of
Biomes.
