Chapter 3 The Biosphere
The Biosphere • A Species is a group of organisms that are so similar to each other that they can breed and produce fertile offspring. 2
SPECIES A miniature poodle and a pit bull are the same species. 3
SPECIES A horse and a donkey can produce babies, but the babies can NOT reproduce, so a horse and a donkey are separate species and their babies are called mules. 4
SPECIES The bearded dragon is a species. 5
A Population is a group of the same species that lives in the same area. 6
POPULATION This group of bearded dragons in Australia is a population. 7
A Community is all of the living things in an area. 8
COMMUNITY The bearded dragons, the Aborigines, spinifex grasses, acacias, thorny devils, and camels are the community of the Mac. Donnell Ranges. 9
An Ecosystem is the living organisms and the nonliving environment of an area. 10
ECOSYSTEM All of the member of the community of the Mac. Donnell Ranges plus the mountains, sand, climate, and other non-living factors make up the Ecosystem. 11
A Biome is a group of ecosystems that have similar characteristics. 12
BIOME The Mac. Donnell Ranges ecosystem is part of the Western Australian Desert Biome. 13 July 22, 2012 Footer text here

Energy Flow Organisms that make their own food are called Producers. Plants are producers. They make their food by photosynthesis. 21
Energy Flow Organisms that make their own food are also known as Autotrophs. 22
Energy Flow Organisms that get their food and energy from other organisms are called Consumers and are also known as Heterotrophs. 23
Energy Flow Herbivores only eats plants. 24
Energy Flow Bunnies and many birds are herbivores. 25
Energy Flow Carnivores only eat other animals. Wolves are carnivores. 26
Energy Flow Omnivores eat plants and animals. 27
Energy Flow This is my favorite omnivore. 28
Energy Flow A Food Chain is a series of steps in which one organism eats another and then is eaten. 29
Energy Flow A Food Web is a series of interconnected food chains. 30
Cycles of Matter The Water Cycle is the movement of water in different stages (liquid, solid, gas) on the Earth. 31
Cycles of Matter Evaporation is the change from liquid water to atmospheric gas. Transpiration is when water enters the atmosphere from the leaves of plants (product of cellular respiration!) 32
NUTRIENT CYCLES Carbon is the most important element in living things. The Carbon Cycle is the cycle by which carbon is exchanged on Earth in various forms 33
NUTRIENT CYCLES Photosynthesis and Cellular Respiration are two parts of the Carbon Cycle, there are many more. 34
NUTRIENT CYCLES The Nitrogen Cycle is the process by which nitrogen is converted between its various chemical forms 35
NUTRIENT CYCLES Nitrogen is required to build proteins and is part of most plant fertilizers. 36
