level questions: Ecosystems

QuestionAnswer
What is a Ecosystem?-This is an Natural Environment, which has Flora [Plants] and Fauna [Animals] that live and Interact with the Environment -Another way of saying, is the Biotic [Living Things] interact with the Abiotic [Non-living]
Describe the Freshwater Pond Ecosystem, in terms of the Biotic and Abiotic.-Pond Bottom: Little Oxygen or Light is at the Bottom of the pond resulting in Decomposers and Scavengers that live here, who feast on Dead Materials -Mid water: Fishes are the Predator here. The food is either down in the Pond Bottom, or the Surface. Animals can Breathe here using their Skin or Gills -Pond Surface: Plenty of Oxygen and Light here, and Animals can breathe though Lungs, Gills or Skin. Ducks, Water boatmen, tadpoles can be Found here -Pond Margin: The Plants can give a Shelter for Insects and Small Animals. Again, lots of Light and Oxygen here -Above the Pond Surface: Birds like Kingfishers and Dragonflies for Insects dominate it
What are Ecosystems dependent on?-They depend on: -The Climate: Temperature and Rainfall can really determine in what Species can live and Survive -The Soil: Type of Soil determines what Nutrients are Provided to give to the Plants -Water: Water levels can say what Plants and Animals can Thrive
What is the Food Chain-This is how the Living things get their Food -Energy and Nutrients are Passed from 1 Organism, to the Next. -Producer gives the Basic Source of Food, which is fed on, by Consumers.
Use the Freshwater Pond, as an Example of a Food chain-Leaves and Algae [Producer] -Eaten by Caddis [Primary Consumers] -Eaten by Fish [Secondary Consumers] -Eaten by Kingfisher [Tertiary Consumers]
What is the Food Web?-This is simply all the Connections between the Producers and the Consumers in the Ecosystem. -It can show how Connected all the Different Organisms can be
How can the Biotic and Abiotic Components be Changed?-It can be through Natural Factors, or Human Management
What are some of the Changes to an Ecosystem, cause by Natural Factors?-This can be: -Drought -Flood -Fire -Disease
What are some of the Changes to an Ecosystem, caused by Human Management?-More x Animal -Changing the Drainage of Land [Affects the Water Level] -Changing the pH level of the Water -Changing the Nutrient Levels
What could the Consequence be if a Change happens to the Ecosystem?-It could be horrible -The Food Chain might Collapse, which would affect Humanity.
What is a Biome?-A very Large Ecosystem
How can Latitude affect the Climate of the Place? Why?-Lower Latitudes, around the Equator, have the Hottest Temperatures -Higher Latitudes, around the Poles, have the Coldest Temperatures -As you go Further North or South, the Temperature Drops -This happens because of the curvature of the Earth -Areas around the Equator has the Sunlight Concentrating in a smaller area, and the Sunlight has a Smaller area of Atmosphere to go through -Areas around the Poles has the Sunlight going through a Larger Area of the Atmosphere, adding on to the Sun being at a Lower Angle. This results in Less Energy, equalling in Less Temperatures
How can High and Low Pressure affect the Climate of the Place?-When the Temperatures are Different, The Air Pressures are also Different across the World -Low Pressure is when Air Rises. Its called this because the Weight of the Air Above, is Lower than Average -High Pressure is when Air Sinks. Its called this because the Weight of the Air Above, is Higher than Average -Low Pressure Areas are linked with Clouds and Rainfall, because the Rising Air cools down -->condenses--> makes clouds--> Water Droplets increase in Size --> Become to heavy, and Released -In the Equator, Its Low Pressure, and rises A Lot of Air. It has a lot of Rainfall because of this, making Warm and Wet Equatorial Climate [Rainforests] -High Pressure Areas are linked with Dry, warm and Settled. This is because Sinking air equals no Rainfall
How can the Winds affect the Climate of the Place?-Air travels in the Upper Atmosphere, and Sinks at around 30 degrees North/South. Sinking air is High Pressure -The High pressure Areas have Dry and Warm conditions, which makes Hot Desert Climates. [Sahara Desert, Kalahari Desert] -The Winds goes from High Pressure Areas, to Low Pressure Areas, which passes the Air, from which it sank, to it Rising -This Transfer of Air keeps the Pressure Belts in check, which creates Different Global Climatic Zones
In the World Map, what are the 8 Main Biomes?-Tundra -Taiga [Coniferous Forest] -Temperature Deciduous Forest [TDF] -Temperate Grassland -Desert -Tropical Rainforest -Savannah Grassland -Chaparral/ Evergreen Hardwood [Mediterranean]
Describe the Tundra-Found near the Poles -Only a Minute Percentage of Plants and Animals can live here
Describe the Taiga [Coniferous Forest]-Found in Scandinavia, Russia and Canada -Evergreen Trees most Popular -Cool Temperature Climate
Describe the Temperate Deciduous Forest [TDF]-Found through Europe and United States of America -Trees here Lose their Leaves yearly, and have Mild and Wed Conditions, that is known as Temperate Maritime Climate
Describe the Temperate Grassland-Found in Hungary, South Africa, Argentina and the United States of America -Has Grass and Trees that experience a Temperate Continental Climate, which has Moderate Rainfall, and Mild Conditions
Describe the Chaparral [Mediterranean]-Found around the Mediterranean Sea, Coasts of Australia, California.
Describe the Desert-Found near the Tropics of Cancer and Capricorn -Conditions are Very Hot and Dry -Plants and Animals are Adapted to Live in these Harsh Conditions
Describe the Tropical Rainforest-Found near the Equator -Hot and Humid -Many species can be Located here
Describe the Savannah Grasslands-Found in Central Africa, South of India, Northern Australia and Central South America -Simply Long Grasses, with a few Trees -Hot and Dry Conditions
