Study Notes

Ecology Vocabulary

  • Ecology involves the study of biotic (living) and abiotic (non-living) factors, and trophic structure.
  • Habitat is the specific environment where an organism lives.
  • Niche refers to the role and position a species has in its environment
  • Levels of organization include biosphere, ecosystem, community, population, and organism.
  • Aquatic biomes include marine and freshwater environments (standing and flowing).
  • Terrestrial biomes include tropical forests, savanna, desert, chaparral, and temperate grasslands like North American prairie
  • Additional terrestrial biomes are temperate forests, taiga, and tundra.

Population Ecology

  • Population ecology focuses on population density and regulation through density-dependent and density-independent factors.
  • Population ecology uses exponential and logistic models and graphs
  • Carrying capacity is the maximum population size an environment can sustain.

Species Interactions

  • Species interact through pathogens, predation, and predator-prey relationships.
  • Predator-prey adaptations include camouflage, mechanical defense, and chemical defense.
  • Symbiotic relationships include mutualism and herbivory.

Trophic Structure

  • Trophic structure includes producers, primary/secondary/tertiary consumers, detritivores, scavengers and decomposers

Ecosystem Structure and Dynamics

  • Energy flow involves primary/gross/net production, food chains and food webs
  • Energy flow can be represented by an energy pyramid.
  • Ecosystem recycling includes the water, carbon, phosphorus, and nitrogen cycles.

Ecology Questions and Answers

  • A change in a habitat affects the entire ecosystem.
  • Organisms with a broad ecological niche are more likely to survive changes in an ecosystem.
  • Destruction of vegetation by plant disease impacts animal life negatively.
  • It's cheaper to produce grain than meat due to energy transfer efficiency.
  • Decomposers are necessary for the continuation of life on Earth, as they recycle nutrients.
  • The study of interactions between organisms and their environment is ecology.
  • The other major type of factor besides biotic is abiotic
  • Soil is not a biotic factor.
  • An organism's habitat includes biotic and abiotic factors in its surroundings.
  • A single organism corresponds to the organism level.
  • A group of individuals of the same species corresponds to the population level
  • All organisms in a particular area corresponds to the community level
  • All organisms and abiotic factors corresponds to the ecosystem level
  • The biosphere is about 13 miles thick.
  • A large region with a specific climate and plant/animal communities describes a biome.
  • The other major biome type besides aquatic, is terrestrial.
  • Two environments found in aquatic biomes are marine and freshwater.
  • The terrestrial environments are tundra, tropical rain forests, taiga, temperate forests, grasslands, savanna, chaparral, and desert
  • Tundra is a cold, largely treeless environment across North America, Europe, and Asia.
  • Taiga is south of the tundra, north of temperate regions, and dominated by coniferous trees.
  • Aquatic biomes are shaped by the availability of light, water currents, and nutrients.
  • Population ecology studies how and why populations change.
  • Fire and storms are not density-dependent factors that limit population growth.
  • Interspecific competition occurs when species compete for the same limited resource.
  • Carrying capacity is the largest population an environment can support.
  • Competition lowers the carrying capacity of competing populations.
  • A honey bee feeding off nectar displays mutualism.
  • Eating sushi with raw fish and getting a tapeworm displays parasitism.
  • Thorns are a mechanical defense used by prey in predator-prey relationships.
  • Bacteria, viruses, and fungi can be pathogens.
  • An organism's trophic level indicates its position in the sequence of energy transfers.
  • Carnivores are the consumers that eat other consumers in the ecosystem.
  • Carbon is recycled, is a major ingredient in all organic molecules, and can be returned to the atmosphere as carbon dioxide.
  • Phosphorus depends on the weathering of rocks and makes up nucleic acids, phospholipids, and ATP
  • Nitrogen is crucial in protein structure and function, a limiting plant nutrient, and makes up about 80% of Earth’s atmosphere.
