Comparing Ecosystem AQUATIC TERRESTRIAL
Two Main Categories for Aquatic Ecosystems 1. Freshwater Ecosystems consist of moving bodies of water such as rivers and streams These bodies of water are classified based on their nutrient levels: Oligotrophic: A body of water that is LOW in nutrients Eutrophic: A body of water that is RICH in nutrients 2. Marine Ecosystems are mainly oceans (coral reefs) and make up more than 70% of the Earths surface. Most of the water that evaporates in the air (water cycle) is from the oceans
The main factor which determines a terrestrial ecosystem is… CLIMATE These regions are a collection of ecosystems that are similar or related and are called… BIOMES Canada is dominated by four main Biomes GRASSLAND TUNDRA BOREAL TEMPERATE DECIDUOUS FOREST
Comparison Chart TUNDRA Northern most Biome Cold, desert Poor soil quality Supports a small # of species Example: Caribou BOREAL South of the Tundra Largest Biome (~80%) Coniferous (needles)Trees Much diversity Found across every province GRASSLAND Next to deciduous Many types of grasses Some diversity Rich fertile soil Mice, snakes, hawks TEMPERATE DECIDUOUS FOREST Much diversity Fertile soil Deciduous (leaves) trees Many Insects
SOIL Soil is made up of a number of ____. Each layers colour and _____. texture having it’s own distinct ____ The top layer is known as ______. It acts like a litter temperature and reducing blanket limiting _______ water loss. Next is _______, topsoil made up of ______ rocks mixed with humus decaying plant and animal matter called ______ subsoil Below topsoil is ____. It contains more _______ stones and some ________. Organic matter bedrock The bottom layer is called _____. It is a solid rock.
gravity pulls the surface water When it rains, _______ percolation into the ground through a process called ______. water table absorbwhich is Eventually it reaches the _____, like and underground river. Plants _______ the environment water and it gets recycled back intoneutral the acidic basic ______. p. H Soil can be _______, or _____. The ____ determines which type of plants can grow in specific areas
Within both aquatic ecosystems and terrestrial ecosystems you have: Artificial Ecosystems : -An ecosystem planned and maintained by humans Examples: parks, backyard, garden, farms etc… Natural Ecosystems : -An ecosystem not planned and maintained by humans, but Not necessarily untouched Examples: lake, river, forest etc… Ecosystems naturally undergo change, they evolve through A process called…
