Ecology Test #2

the zone that is the deepest part of the ocean and receives no sunlight and is very cold.

intertidal zones, nertic zone, oceanic zone, benthic zone

only biome with 4 changing seasons

animals in this ocean zone get their food by eating material that sinks from above

a complex community characterized by distinctive biotic and aboitic factors

to attract mates, birds will dance & make noises by chirping. What type(s) of communication is this? Mark all that apply

An organism that is not native to an ecosystem and causes negative effects to the environment, economy, or human health

on a climograph, months of the year are shown where?

this biome has a layer of permafrost

this biome is very hot and dry

this biome has scattered clumps of trees and seasonal rains

_______________ is light produced by a chemical reaction in an organism to communicate by ____________

first organisms to live in an area

lichen breaks down rock in primary succession

the zone where the ocean floor starts to slope downward. The water is warm and receives a lot of sunlight.

monkeys "making faces" or moving their body in a specific way is what kind of communication?

Skunks spray a chemical when it feels threatened. How is the skunk communicating to others?

this biome holds some of the smallest and largest organisms

most primary succession begins with...

receives less than to 250 mm of precipitation. 4 types: hot and dry, semiarid, coastal, cold

what graph do you use to record precipitation on a climograph

the zone where the ocean meets the land. This area is exposed to air for part of the day

Otters often hold hands and cuddle to comfort their young. What type of communication is this?

extremely cold climate with low biotic diversity

small community growing in a series of stages in an area where other organisms had not previously lived-no soil present

any way in which animals share information

succession that occurs in an area with no soil is...

the average weather of a specific region year after year. Determined by precipitation and temperature

this biome has the greatest diversity of plants and animals

this biome consists of ponds, rivers, streams

sight, sound, scent, touch

this zone is where no sunlight reaches. The organisms that live here often feed on dead organisms that sink from above

Fire flies communicate through ____________ by flashing their bioluminescent light to ________________

this succession can be caused by a volcanic eruption or slowly retreating glacier.

this zone extends from the littoral zone across the top of the water. This zone goes as deep as sunlight can reach.

this is the layer below the top layer of soil that is permanently frozen

this biome has trees that produce seeds in cones

a stable, mature community that has reached the final stages of succession

littoral zone, open-water zone, deep water zone

this biome has trees that lose their leaves in the fall/winter

natural disasters like drought and/or fires or by human disruption

This zone is the area closest to the edge of the water. Sunlight reaches the bottom of this zone.

the zone where the ocean floor drops suddenly. This zone contains the deep water of the open ocean.

in secondary succession there needs to be soil present

what graph do you use to record temperature on a climograph

what is the main goal of pioneer species in primary succession?

can spread due to human activities, climate patterns, or migration

a series of regrowth after a disturbance to an ecosystem- there is soil present

the replacement of one type of community by another at a single place over a period of time
