Ecology Test #2 2024

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

physical space where an organism makes its home

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

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

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

organisms that break down dead material to obtain chemical energy

a community of different species and their interactions with each other and their physical environment

intertidal zones, nertic zone, oceanic zone, benthic zone

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

this biome has a layer of permafrost

what eats the secondary consumer?

this biome holds some of the smallest and largest organisms

in secondary succession there needs to be soil present

lichen breaks down rock in primary succession

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

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

this biome has scattered clumps of trees and seasonal rains

this biome has the greatest diversity of plants and animals

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

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

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

what graph do you use to record precipitation on a climograph

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

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

first organisms to live in an area

a complex community characterized by distinctive biotic and aboitic factors

An organism's role in its environment, how it "fits in"

What is the role of the foxes in this food web?

why do animals communicate? choose all that apply

consumers make their own energy

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

littoral zone, open-water zone, deep water zone

this biome is very hot and dry

only biome with 4 changing seasons

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

Autotroph

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

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

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

most primary succession begins with...

this biome has trees that produce seeds in cones

what graph do you use to record temperature on a climograph

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

carnivores eat meat and plants

this biome consists of ponds, rivers, streams

an organism that only eats plants

any way in which animals share information

Which organism in this food web is a producer?

producers eat first in the food chain

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

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

heterotrophs cannot make their own energy and have to get it from somewhere else

extremely cold climate with low biotic diversity

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.

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

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

What is one way food chains and energy pyramids are similar?

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

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

organisms that eat organisms that they did not kill themselves

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

sight, sound, scent, touch

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

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