Levels of Organization
All life on Earth and all parts of the Earth in which life exists, including land, water, and the atmosphere is called
the biosphere
Any living component of the environment with which an organism might interact
Biotic Factor
These are the first producers of energy-rich compounds that are later used by other organisms.
Primary producers
Animals that kill and eat other animals are
Carnivores
Observation
Population
Abiotic Factor
This is the process in which light energy is captured and used to power chemical reactions.
Photosynthesis
Organisms that obtain energy and nutrients by eating plants or parts of plants
Herbivores
Experimentation
A group of similar organisms that can breed and produce fertile offspring is
Humidity, precipitation, sunlight, heat, etc. are examples of
Abiotic Factors
In hydrothermal vents and deep ocean floor, what method would autotrophs use to produce energy-rich compounds?
Chemosynthesis
A King Vulture is considered a scavenger
Observation
Different populations that live together in a defined area is called
Community
Leaf mold, and fungi are examples of
Biotic Factors
Algae, cyanobacteria
How do organisms such as bacteria and fungi obtain nutrients and energy?
They chemically break down organic matter
The best ecological method to use when studying events that take place over large periods of time or regions is
Examples of this level of organization include, tundra, savannah, marine, desert, forest
Biome
Interdependence in nature
What are the main photosynthetic producers on Earth?
Plants
Organisms that feed on detritus particles are called
Detritivores
The best method to use to study ecological phenomena such as hurricanes and tsunamis is
Modeling
