Mutualism
Both organisms benefit from their relationships
Which equation is the correct process of photosynthesis?

Passed the US invasive act
Parasitism
Relationship in which one organism benefits while the other organism is harmed
native species
Species that normally live and thrive in a particular ecosystem
Commensalism
The relationship benefits one organism while the other organism remains unaffected

Cellular respiration creates ___
carbon dioxide
How do consumers obtain their energy?
cellular respiration
Territory defense
controls population ; reduces competition
Animals that have a strong territory defense ___ competition for food sources in that region.
decreases
Precipitation decreases and temperature increases drastically in an area, causing local fauna (animals) to relocate. This is an example of a ____
density independent

it cannot respond to its environment
What are invasive species threatening to native species?
native species don't have defenses against invasive species
What does NOT limit population growth rates?
natural disasters
Competition
●Multiple organisms rely on the same limited resources (food, habitats, etc) ○Can occur between different species or the same species
Predation
●One organism eats another (predator-prey) ●Top predators are at the top of the food chain/web
Which of these is a common decomposer?
bacteria
Tundras have very little vegetation, mostly grasses and small shrubs. These plants have short enough root systems that avoid the layer of permafrost below, allowing the plants to thrive in this cold and dry environment. What type of adaptation is this?
physical
Amount of predators in an area is a density dependent
population factor
Omnivore
primary and secondary consumer
herbivore
primary consumer
Autotroph
producer

protein synthesis and making DNA
Symbiosis
relationship between two organisms (of different species) living in the same ecosystem
Carnivore
secondary consumer
Why are adaptations important?
they help an organism survive in their environment

to attract potential mates

towards the equator mountainous areas
Animals that have a strong territory defense decreases competition for food sources in that region.
true
