Biotic Relationships:Community Interactions
Biotic Relationships Competition Predation Symbiosis
Competition Examples:Organisms attempt to use a resource in the same place at the same time Examples: Water Nutrients Light Food space
Predation One organisms captures and feeds on anotherPredator is the killer/eater Prey is the food
Symbiosis Any relationship in which two species live closely togetherThree main classes: Mutualism Commensalism Parasitism
Mutualism Both species benefit Example: flower and bee
Commensalism One benefits, the other is neither benefited nor harmedExample: barnacles and whale Barnacle filter feeds
Parasitism One benefits, the other is harmedParasite lives on or in the host, and obtains some/all of its nutrients from host Examples: tapeworms, fleas, ticks, lice
What type of relationship?Remora and shark Remora uses shark for transportation and eats the shark’s leftover food
What type of relationship?
What type of relationship?
What type of relationship?Clownfish clean anemones Sea anemones provide protective habitat
SPECIES INTERACTIONS. Community Interactions Competition – occurs when organisms of the same or different species attempt to use an ecological resource.
Relationships Among Organisms Biology EOCT Review.
Ecological Relationships. Competition and Predation Competition – occurs when organisms of the same or different species attempt to use an ecological.
Chapter 17 Section 1 How Organisms Interact in Communities.
Relationships in the Ecosystem
Anchor: BIO.B.4.2 Describe interactions & relationships in an ecosystem ◦ BIO.4.2.2: Describe biotic interactions in an ecosystem.
Community Interactions. Community interactions, such as competition, predation, and various forms of symbiosis, can powerfully affect an ecosystem.
Ecosystem Interactions Interactions The organisms in a community are capable of interacting with each other in some very complex ways. – They can: Hurt.
Community Interactions Community: Many different species interacting in the same environment. Three types of interactions: – Competition – Predation.
Review: Levels of organization ORGANISM POPULATION COMMUNITY ECOSYSTEM BIOME BIOSPHERE.
Community Interactions. Community All the living organisms in an area at a certain time All the living organisms in an area at a certain time.
Ecology Chapter 2. What is Ecology? Ecology is the study of interactions that take place between organisms and their environment. Ex. Bird on a tree limb.
AutotrophHeterotroph. Food Web Energy Flow Energy Pyramids:
What is the greenhouse effect?. AGENDA: 1.Finish PSQ: Greenhouse Effect 2.Notes 4-2: What shapes an Ecosystem? 3.Using Predators to Manage Population.
Niche & Community Interactions
Niches and Community Interactions
SYMBIOTIC RELATIONSHIPS WORDS 10-15
Shaping an Ecosystem. Biotic and Abiotic Factors Ecosystems are influences by living and non living Biotic factors: all biological factors in an ecosystem.
4.2 Niches and Community Interactions
The full range of physical and biological conditions in which an organism lives and the way in which they use those conditions. Niche.
Lesson Overview Lesson Overview Niches and Community Interactions Objectives 4.2 Niches and Community Interactions - - Define niche. -Describe the role.
Species Interactions. Niche (“nitch”) A species role in its ecosystem Ex - Spiders eat many smaller insects, bees help to pollinate flowers. No two species.
Competition, Predation and Symbiosis
Community Interactions Unit 6: Ecology. Niche Full range of physical and biological conditions in which an organism lives The way in which the organism.
1.3 Interactions among living things. Adapting to the environment – Natural selection – A process by which characteristics that make an individual better.
Relationships in the Ecosystem. What are the types of relationships? 1)Predator / Prey 2)Competition 3)Symbiosis A) commensalism B) mutualism C) parasitism.
Population Interactions. Ecosystems are made of many populations living together How do populations live together? ◦ 5 types community interactions.
Community Interactions. Community group of different populations living in the same ecosystem. includes all of the living things in an ecosystem.
Interrelationships Working together to remove the bad guy.
Ecosystems and Communities. Climate vs. Weather Weather – day to day conditions in a particular place at a particular time. Climate – avg. of temperature.
ECOSYSTEMS AND COMMUNITIES. Learning Goal: In this lesson we will learn about abiotic and biotic components of an ecosystem. We will also learn about.
Objectives 4.2 Niches and Community Interactions
Ch.21 Populations & Communities Section 3: Interactions Among Living Things.
Ecosystems Chapter 4. What Shapes an Ecosystem? Biotic Factors: biological influences on organisms - any living thing that an organism interacts with.
Welcome Back Future Scientists!.
All living things interact with their environment, both biotic and abiotic Most living things produce more offspring than can survive.
Community Interactions Community: Many species interacting in the same environment Three types of interactions: – Competition – Predation – Symbiosis.
4.2 Ecosystems and Communities By: Deborah Lamoreaux.
Competition, Predation and Symbiosis. Niche Every organism has a variety of abilities or adaptations that are suited to its specific living conditions.
What Shapes an Ecoysystem?
Chapter 8 How Species Interact with Each Other
Symbiotic Relationships Mutualism- benefits both organisms Commensalism- benefits one and the other is neither helped nor harmed Parasitism- benefits one.
Interactions Between Organisms. Symbiosis Symbiosis occurs when two species live closely together in a relationship that lasts over time If you’ve.
OBJECTIVE: Identify Different Interactions among speciesInteractions.
