Definition: A complex relationship between the living organisms, habitats, and resources of a given area. Organism are typically dependent on each other and their habitat for survival. They can be natural or artificial 2 M.Bregar (Dante C.S.S.) What is an Ecosystem? : What is an Ecosystem? M.Bregar (Dante C.S.S.) 3 Natural Ecosystem Artificial Ecosystem Slide 4: M.Bregar (Dante C.S.S.) 4 What type of ecosystem is this? Monoculture Forest vs Natural Forest : Monoculture Forest vs Natural Forest M.Bregar (Dante C.S.S.) 5 Homes and Habitats : Homes and Habitats The place where an animal lives is called its habitat. An animal lives where it can find food, water, shelter and a mate. 6 M.Bregar (Dante C.S.S.) Slide 7: 7 M.Bregar (Dante C.S.S.) What is an Ecosystem? : What is an Ecosystem? Ecosystems share similar: Abiotic Factors: temperature, rainfall, etc. Biotic factors: types of living organisms Ecosystems can be large or small, the key idea is that they share similar factors! 8 M.Bregar (Dante C.S.S.) Slide 9: M.Bregar (Dante C.S.S.) 9 Slide 10: M.Bregar (Dante C.S.S.) 10 What is an Ecosystem? : What is an Ecosystem? M.Bregar (Dante C.S.S.) 11 The “largest ecosystems” are called biomes. There are many biomes, including such as the Desert, Tundra, Tropical Rainforest, etc. Slide 12: M.Bregar (Dante C.S.S.) 12 What is an Ecosystem? : What is an Ecosystem? Living organisms in an ecosystems are “classified” into: 13 M.Bregar (Dante C.S.S.) POPULATIONS COMMUNITIES Total individuals belonging to ONE SPECIES in a habitat All the combined populations in a habitat Living Things : Living Things All living things (organisms) need food (nourishment) to live. Living things in an ecosystem depend on each other for food. 14 M.Bregar (Dante C.S.S.) Carnivores : Carnivores Some animals, like the kingfisher, eat only other animals. These animals are called “carnivores”. 15 M.Bregar (Dante C.S.S.) Slide 16: 16 M.Bregar (Dante C.S.S.) Carnivores : Carnivores M.Bregar (Dante C.S.S.) 17 Adaptations for killing such as sharp teeth, claws, strong jaws, binocular vision, and venom. Ex. – carnivores have large canines for tearing flesh Carnivores : Carnivores M.Bregar (Dante C.S.S.) 18 Carnivores(In class) : Carnivores(In class) M.Bregar (Dante C.S.S.) 19 Behavioral adaptations such as “stalking” & pack hunting Carnivores(Online) : Carnivores(Online) M.Bregar (Dante C.S.S.) 20 Carnivores – Wolves pack-hunting (In class) : Carnivores – Wolves pack-hunting (In class) M.Bregar (Dante C.S.S.) 21 Carnivores – Wolves pack-hunting (Online) : Carnivores – Wolves pack-hunting (Online) M.Bregar (Dante C.S.S.) 22 Carnivores – Snakes(In class) : Carnivores – Snakes(In class) M.Bregar (Dante C.S.S.) 23 Carnivores – Snakes(Online) : Carnivores – Snakes(Online) M.Bregar (Dante C.S.S.) 24 Herbivores : Herbivores Some animals do not eat other animals. They survive on plants and are known as “herbivores”. 25 M.Bregar (Dante C.S.S.) Slide 26: 26 M.Bregar (Dante C.S.S.) Herbivore : Herbivore M.Bregar (Dante C.S.S.) 27 Adaptations for obtaining and eating plant material such as specialized teeth, flexible necks, and strong jaws. Ex. – herbivores have large molars for chewing plant material Herbivore Adaptations (In class) : Herbivore Adaptations (In class) M.Bregar (Dante C.S.S.) 28 Herbivores have adaptations to avoid being eaten. Herbivore Adaptations (Online) : Herbivore Adaptations (Online) M.Bregar (Dante C.S.S.) 29 Defence to Wolves pack-hunting (In class) : Defence to Wolves pack-hunting (In class) M.Bregar (Dante C.S.S.) 30 Defence to Wolves pack-hunting (Online) : Defence to Wolves pack-hunting (Online) M.Bregar (Dante C.S.S.) 31 Omnivores : Omnivores Some animals, like us, eat both plants and animals making them omnivores. Omnivores have characteristics of both carnivores and herbivores 32 M.Bregar (Dante C.S.S.) Slide 33: 33 M.Bregar (Dante C.S.S.) Slide 34: 34 M.Bregar (Dante C.S.S.) Scavengers : Scavengers M.Bregar (Dante C.S.S.) 35 Animals which consume the carcasses left by larger predators. Example: crows and vultures Move around searching for carrion (dead flesh) Scavengers : Scavengers M.Bregar (Dante C.S.S.) 36 Animals which consume the carcasses left by larger predators. Example: crows, vultures, hyenas Move around searching for carrion (dead flesh) or any other food sources Scavengers : Scavengers M.Bregar (Dante C.S.S.) 37 Many organisms turn to scavenging as a means of survival, but they are not “true scavengers” Very few animals are “true scavengers” Slide 38: M.Bregar (Dante C.S.S.) 38 Scavengers : Scavengers M.Bregar (Dante C.S.S.) 39 Hyenas have been viewed as scavengers, but they are also predators. Scavengers(In class) : Scavengers(In class) M.Bregar (Dante C.S.S.) 40 Scavengers(Online) : Scavengers(Online) M.Bregar (Dante C.S.S.) 41 Detritivores : Detritivores M.Bregar (Dante C.S.S.) 42 Organisms which eat detritus, such as worms, beetles, millipedes, etc. Detritus is dead plant/animal material These organisms will move from food source to food source Involved in the process of decomposition Decomposers : Decomposers M.Bregar (Dante C.S.S.) 43 Organisms that consume dead or decaying organisms, this is called decomposition Decomposers actually “live on their food” Primary decomposers are bacteria and fungi FOOD CHAINS : FOOD CHAINS 44 M.Bregar (Dante C.S.S.) Food Chains : Food Chains Diagram showing “who eats who” within a ecosystem Illustrates the flow of organic matter and energy within an ecosystem. Arrows represent the flow of energy. 45 M.Bregar (Dante C.S.S.) Food Chains : Food Chains A food chain shows what is eaten. The fly is eaten by the thrush. 46 M.Bregar (Dante C.S.S.)

So do bears! 48 M.Bregar (Dante C.S.S.) Prey : Prey Any animal which is hunted and killed by another animal for food is prey. Predator Prey 49 M.Bregar (Dante C.S.S.) Roles in a Food Chain : Roles in a Food Chain Within an ecosystem, organisms have different roles they take place within a food chain. The 3 roles are: (1) Producers, (2) Consumers, and (3) Decomposers 50 M.Bregar (Dante C.S.S.) Food Chains : Food Chains 51 M.Bregar (Dante C.S.S.)

Plants need light for photosynthesis, what else do they need? : Plants need light for photosynthesis, what else do they need? We call plants producers because they produce energy from the sun directly. 53 M.Bregar (Dante C.S.S.) Photosynthesis : Photosynthesis Photosynthesis: the process in which plants make sugar from sunlight 54 M.Bregar (Dante C.S.S.) Producers : Producers Living things which can make their own food from NON-LIVING THINGS, such as plants or algae Producers are: autotrophs Source of all chemical energy in an ecosystem They trap sunlight and store it as food energy (chemical energy) 55 M.Bregar (Dante C.S.S.) Consumers : Consumers “Consume” means “eat”. Animals are consumers because they “eat” (consume) food provided by plants or other animals. 56 M.Bregar (Dante C.S.S.) Consumers : Consumers Living things which must eat other living things for energy Consumers are: Heterotrophs Various types of consumers: herbivores, carnivores, or omnivores 57 M.Bregar (Dante C.S.S.) Decomposers : Decomposers Living things which use waste and dead material for food Examples: bacteria and fungi They are heterotrophs 58 M.Bregar (Dante C.S.S.) Decomposers : Decomposers Help return raw materials and nutrients to the environment 59 M.Bregar (Dante C.S.S.) Biodegradation : Biodegradation M.Bregar (Dante C.S.S.) 60 This is the recycling of nutrients. Completed by decomposers Slide 61: 61 M.Bregar (Dante C.S.S.) Producers / Consumers Game : Producers / Consumers Game 62 M.Bregar (Dante C.S.S.) Some Key Terms: : Some Key Terms: Important Key Terms: AUTOTROPHS: organisms which make their own food from non living things. HETEROTROPHS: organisms which must feed on other living things for food. 63 M.Bregar (Dante C.S.S.) Food Chain Game : Food Chain Game 64 M.Bregar (Dante C.S.S.)
