Biotic parts+1 example
Living organisms that reside within an ecosystem
Ex: Cat, sunflower, kelp, cyanobacteria
Mutualism+1 example
Both organisms benefit
++
Ex: Clownfish living in sea anemone
Two organisms live adjacently, which can be any relationship
Symbiosis
Endangered vs Threatened
Endangered- on the verge of extinction
Threatened- predicted to be endangered soon in the anticipated future
Primary producer example
Phytoplankton, rose, cypress, acacia
The study of the interactions between species and their environment
Ecology
Competition+1 example
Organisms fight over the same resource, both losing energy and possibly their life
--
Ex: mussels fighting for space in rocky intertidal zone
List the three areas in the order as described:
1. Exists anywhere the ocean meets the land
2. Contains "forests" of rapidly growing protists that dampen wave action, reduce coastal erosion, and enhance recruitment of fish
3. Coastal regions on land that have mild winters and dry and hot summers
1. rocky intertidal zone
2. kelp forest ecosystem
3. chaparral biome
Endemic vs Invasive
Endemic- Species that are native to and found only in a single limited geographic area
Invasive- Organisms from another world region that shouldn't be in their new environment (often introduced by careless humans) and that function differently, frequently harming ecosystems
A tiger shark living in a warm bay in Florida is a/an...
An apex predator
Abiotic parts+1 example
Non-living, (not dead) parts of the ecosystem that affect the environment
ex: temperature, water, wind, minerals...
Predation/herbivory+2 examples
When one organism eats another (if the organism eats a plant it is called herbivory)
+-
Ex:
P- Wolf hunting deer
H- Giant panda eating bamboo
Outlines who eats whom
Food chain
Species
A group of similar organisms that can reproduce fertile offspring
A squirrel that only eats berries and other plant matter is a/an...
A primary consumer
Terrestrial vs Marine
Name an organism that would live in a terrestrial ecosystem, and then one that inhabits a marine ecosystem.
Terrestrial is a land-based environment
Marine is an ocean-based environment
Ex:
T- cactus, cow, oak tree
M- red algae, blue whale, sea worm
Parasitism+1 example
When an organism feeds off another organism and slowly consumes it, or transmits disease
+-
Ex: ticks on human
Contains many entangled food chains combined in the ecosystems
Food web
Population
All organisms of the same specific species that can reproduce among each other at the same place, at the same time
An omnivore would most certainly NOT be a...
Largest of all aquatic (underwater ecosystems) with a high salt content, unique because of turbidity, oxygen, light, sound, water quality, temperature, and depth.
Marine ecosystem
Commensalism+1 example
When one organism benefits but the other is not bothered, disturbed, or harmed
+0
Ex: barnacles living on whales for free transportation to food
What is trophic structure?
The subdivisions between trophic levels in which amounts of biomass are passed up
Community
Interacting groups of diverse, different species at the same place, at the same time
A snake that only eats rabbits but gets eaten by hawks would be a/an...
A secondary consumer
