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

Which of the following is NOT a characteristic of a living organism?

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

Where do we see an increase in biodiversity?

towards the equator mountainous areas
