Ecology By: Anthony Michielini
What is ecology?
study of how organisms interact with each other and how they interact with their environment
What is Individual organisms?
Smallest unit of study that ecologists concern themselves with.
What are Species?
same type of organism that lives in the same place at the same time. capable of reproducing and producing fertile young
What are Populations?
groups of the same species that may or may not interact with each other. Many different ways to divide up population
What is Communities?
Groups of populations that are interacting with each other at any given day or any given time
What is an Ecosystems
Lots of habitats in a generalized area put many ecosystems together and you get a biome.
What’s a Biosphere?
All of the places on earth that living things survive, anywhere there is life would contribute to the biosphere
What’s a Habitat?
Groups of communities all with very similar biotic and abiotic conditions
What’s Abiotic Factors?
Non living things
What’s Biotic Factors?
What are producers(first Tropic level)?
Autotrophs - Producers, plants – Gets energy from the sun – most energy is found here Biggest level
What are Primary Consumers (Second Tropic Level)?
First level consumer – herbivore 90% of energy is lost as you move up the pyramid
What are Secondary Consumers (Third Tropic Level)? – Carnivores or omnivores 10% of energy is left over on this level
Tertiary Consumer (Fourth Tropic Level)?
– Carnivores of omnivores 1% of energy is left over on this level for those organisms to use
What are Quandary Consumer (Fifth Tropic Level)?
Very little energy at this level Usually rare to be at this level
What is the difference from a food pyramid and a food web?
Food pyramid – like a chain with a specific order Food web – more complicated with different paths being followed
What is a Decomposer?
Similar to saprobes recycle nutrients back into the soil as they consume the dead EX: bacteria, mushrooms, and insects
What is an Autotroph?
An organism that makes its own food. EX: plants and algae
What is a Heterotroph?
organism that obtains its nutrients from other organisms. EX: humans, lions, and mushrooms
What is a herbivore?
Something that only eats plants. EX: giraffe and elephant
What is a Carnivore?
Organism that only eats meat EX: lions, tigers, and bears
What’s an omnivore?
Something that eats both meat and plants EX: humans
What is a saprobe?
A decomposer Gets rid of remaining material when things die
What is a scavenger?
Something that eats other dead organisms EX: crow and hyena
What is Amensalism?
organism benefits and kills the other organism EX: Black walnut tree, penicillin
What is Commensalism?
organism benefits and other in not harmed or benefited. EX: shark and a suckerfish
What is Parasitism?
organism benefits, and the other is harmed EX: ticks, fleas, leaches, tape worms If it kills their host they lose their food source
What is Mutualism?
organism get something good from the relationship EX: tick birds sitting on rhinos and eat the ticks. Birds have food, and the rhino is cleared of ticks
What is Symbiosis?
Its between two or more organisms, and how they interact with each other.
What are some limiting factors?
Food, water, money, and shelter.
What is Density Dependent?
EX: food - more organisms you have the less food you have.
What is Density Independent?
All are equally affected, does not matter how many people there are EX: earthquakes volcanic, eruptions etc.
What is Competition between and among Species?
Competition between species – food, water, and shelter Among Species – same things(from above) and mates
What is carry capacity?

Ecology Quiz Review.
DO NOW Answer the following: What is Ecology?.
Ecology Chapters 3, 4 and 5. What is Ecology Interactions between living and nonliving things or the biotic and abiotic. Biotic – all living organisms.
Chapter 16 Notes Interactions of Living Things
ECOSYSTEMS. ECOSYSTEMS & ECOLOGY Ecology is the study of the interactions of living organisms with one another and their physical environment.

ECOLOGY The Study of the Interaction of organisms with their environment.
Unit 2, Part 3 Notes Food Chains, Food Webs, and the Transfer of Energy.
Ecology: The study of Interactions among Organisms and its environment including: Abiotic factors are nonliving factors such as temp. soil, air, rocks.
Energy Flows Trophic Levels and Food Pyramids. Autotrophs A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide.
