Relationships What are the relationships between organisms in an ecosystem? Vocabulary (Add to the top of the page) • Niche: Vocabulary (Add to the top of the page) • Niche: the role or “job” an organism plays in an ecosystem Producer/Consumer Relationships • Producer – all _______________; trap energy from the sun Ex: plants, green algae, phytoplankton Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all _______________: they ingest food containing the sun’s energy Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat ___________ • Ex: rabbit, caterpillar Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat plants • Ex: rabbit, caterpillar Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat plants • Ex: rabbit, caterpillar • Secondary, tertiary, etc….consumers • Carnivores – eat __________ Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat plants • Ex: rabbit, caterpillar • Secondary, tertiary, etc….consumers • Carnivores – eat meat Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat plants • Ex: rabbit, caterpillar • Secondary, tertiary, etc….consumers • Carnivores – eat meat • Omnivores – eat ___________ Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat plants • Ex: rabbit, caterpillar • Secondary, tertiary, etc….consumers • Carnivores – eat meat • Omnivores – eat both (plants and meat) Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat plants • Ex: rabbit, caterpillar • Secondary, tertiary, etc….consumers • Carnivores – eat meat • Omnivores – eat both (plants and meat) • Decomposers – _________________dead matter into simpler molecules that can be absorbed • Ex: fungi Producer/Consumer Relationships • Producer – all autotrophs; trap energy from the sun Ex: plants, green algae, phytoplankton • Consumer – all heterotrophs: they ingest food containing the sun’s energy • Primary consumers: • Herbivores – eat plants • Ex: rabbit, caterpillar • Secondary, tertiary, etc….consumers • Carnivores – eat meat • Omnivores – eat both (plants and meat) • Decomposers – break down dead matter into simpler molecules that can be absorbed • Ex: fungi Predator/Prey Predation • Relationship in which one organism _____________ and one ___________ Predator/Prey Predation • Relationship in which one organism benefits and one dies Predator/Prey Predation • Relationship in which one organism benefits and one dies • Living organism = Predator/Prey Predation • Relationship in which one organism benefits and one dies • Living organism = predator (hunting, hunter) Predator/Prey Predation • Relationship in which one organism benefits and one dies • Living organism = predator (hunting, hunter) • Dead organism = Predator/Prey Predation • Relationship in which one organism benefits and one dies • Living organism = predator (hunting, hunter) • Dead organism = prey (hunted) Predator/Prey Predation • Relationship in which one organism benefits and one dies • Living organism = predator (hunting, hunter) • Dead organism = prey (hunted) • Ex: Lion and Zebra Predator/Prey Predation • Relationship in which one organism benefits and one dies • Living organism = predator (hunting, hunter) • Dead organism = prey (hunted) • Ex: Lion and Zebra • Other examples? Symbiosis • ________________________________________________________ ________________________________________________________ Symbiosis • Two or more different species living together (interactions) Symbiosis • Two or more different species living together (interactions) • 3 relationships: Symbiosis • Two or more different species living together (interactions) • 3 relationships: • Mutualism Symbiosis • Two or more different species living together (interactions) • 3 relationships: • Mutualism • Parasitism Symbiosis • Two or more different species living together (interactions) • 3 relationships: • Mutualism • Parasitism • Commensalism Note (add to the page somewhere) • Neutralism IS NOT a symbiotic relationship Mutualism • Relationship in which both organisms ______________ Mutualism • Relationship in which both organisms benefit Mutualism • Relationship in which both organisms benefit • Ex: cows and white headed cow bird (bird eats insects off cow, preventing illness) Mutualism • Relationship in which both organisms benefit • Ex: cows and white headed cow bird (bird eats insects off cow, preventing illness) • Other examples? Parasitism • Relationship in which one organism ____________ and one is ______________ Parasitism • Relationship in which one organism benefits and one is harmed Parasitism • Relationship in which one organism benefits and one is harmed • Ex: fleas and dogs, mosquitoes and humans Parasitism • Relationship in which one organism benefits and one is harmed • Ex: fleas and dogs, mosquitoes and humans • Other examples? Commensalism • Relationship in which one organism ____________ and the other organism is ___________________________________ Commensalism • Relationship in which one organism benefits and the other organism is neither helped nor harmed Commensalism • Relationship in which one organism benefits and the other organism is neither helped nor harmed • Ex: whales and barnacles Commensalism • Relationship in which one organism benefits and the other organism is neither helped nor harmed • Ex: whales and barnacles • Other examples? Competition __________________________ Competition for the same limiting resources Competition for the same limiting resources • Instraspecific Competition– organisms of the __________ species fight for the same resource. Competition for the same limiting resources • Intraspecific competition – organisms of the same species fight for the same resource. • Ex: two bucks competing for a mate Competition for the same limiting resources • Intraspecific competition – organisms of the same species fight for the same resource. • Ex: two bucks competing for a mate • Interspecific competition – organisms of _____________ species fight for the same resource Competition for the same limiting resources • Intraspecific competition – organisms of the same species fight for the same resource. • Ex: two bucks competing for a mate • Interspecific competition – organisms of different species fight for the same resource • Ex: seals and sea lions compete for fish
