To understand a world biome, you need to know:
• What the climate of the region is like including temperature & precipitation patterns.
• Where each biome is found and what its geography is like.
• The types of plants found in the biome.
• The types of animals found in the biome.

Freshwater
![Page 30: Biomes of Earth Unit 1 S7L4.e. EQ: What are the 6 major biomes on the Earth?](https://reader035.vdocuments.mx/reader035/viewer/2022081514/56649cad5503460f9496f967/html5/thumbnails/30.jpg)
Freshwater Streams & Rivers:
Streams - Animals are adapted to strong currents (insects & small animals have hooks or suckers
to cling to rocks). Trout live here but few plants & algae so leaves and seeds provide food.
Rivers – Cloudy with soil, Plants take root, frogs, fish.
Ponds & Lakes:
Standing or still fresh water. Lakes are larger & deeper than ponds.
Ponds – plants can grow, catfish
Lakes – plants & algae float, dragonflies, turtles, snails, frogs, fish

All marine ecosystems are based on saltwater
Intertidal Zone: shoreline, animals (barnacles, sea stars, clams, & crabs)
Neritic Zone: photosynthesis can occur. Rich in living things, large schools of
fish (sardines), algae, coral reefs
Oceanic Zone: surface zone w/algae & Deep zone w/giant squids
Benthic Zone: ocean floor, organisms include bacteria, works, sea urchins
