exam 3

why does a tropical rainforest have a higher biodiversity than the tagia?

The warm constant temperature and abundant rainfall allows for the growth of many plants, these in turn Support many and diverse animals and the tagia has seasonal variations in temperature as well as plant growth which restrict the number and variety of animal types

what is the northern most terrestrial biome and what are the dominant plant types

The northernmost terrestrial biome is the Arctic tundra and the dominant plant types are mosses, lichens and grasses

key features of the lake ecosystem

Lakes have 3 life zones.

littoral zone, along shore where most of the life is.

limnetic zones where it is too deeprooted, vegetation and the profondel which is the bottom of the lake where it is to dark for Photosynthesis

(During the summer and anter there are also temperature zones while the spring and fall have "turn over”

epiphytes

air plants that grow on trees instead of soil

Jungels

Areas of forest that are open to the sunlight and as results have very dense plant growth (ex: edges of roads, streams, rivers or where large tree here fallen down)

Ecological succession

The gradual change in a community overtime

Life Zones

littoral zones, limnetic zone, Profundal zone

Littoral zone

Along shoreline water is shallow enough for rooted plants.

limnetic zone

open water area which is in Contact with the air

Profundal zone

Below limnetic Zone too little light for photosynthesis

Biome

A large region with similar Climate and Living organisms

which biome receives very little rainfall?

Dessert

what usually grows first on bare rock during Primary succession

Pioneer species such as liches

what is an estuary

An area where freshwater mixes with saltwater

why are cutlands important?

They fiter water and provide habitat

Coral reefs are typically found?

In warm, shallow waters

what is the main direction that water flows in a stream

Downhill

which aquatic ecosystem has the higest salt Content?

Ocean

which factor most strongly Influences the types of organisms found in a biome?

climate

value of wetlands

Purify water

Help absord overflow and prevents flooding

Provide a home for organisms that are the ink in various food chains

most of the life in the ocean is located here

costal waters
