Ecological relationships
This document discusses ecological relationships between organisms in a forest reserve. It defines key terms like symbiosis, trophic levels, and food chains. The goal is to have students name plant and animal species in the forest, and identify an ecological relationship between two species that promotes a healthy environment. Students will learn about different types of symbiotic relationships like mutualism and how energy is transferred between trophic levels in a food chain.

Editor's Notes
- #5 We will be looking at relationships between species within ecosystems.
- #8 is the scientific study of the relations that living organisms have with respect to each other and their natural environment.
- #12 attack of the killer fungi - Planet Earth Attenborough BBC wildlife
- #16 It is a relationship in which both organisms are benefited
- #17 The territorial fish protects the anemone from anemone-eating fish. In turn the stinging tentacles of the anemone protect the clownfish from its predators.
- #18 Ants feed on the sugary honeydew left behind by aphids. In exchange, the ants protect the aphids from predators and parasites.
- #19 It is a permanent association of two organisms in which one partner receives the benefit while the other one is neither benefited or injured.
- #20 the bird gets the left over food off the alligators teeth.
- #21 remora fish are very bony and have a dorsal fin (the fin on the back of fish) that acts like a suction cup. Remora fish use this fin to attach themselves to whales, sharks, or rays and eat the scraps their hosts leave behind.
- #22 One organism (parasite) lives at the expense of the other (host)
- #23 Female mosquito (unaffected) and human (affected) Parasite is transferred by bites from the female mosquito Mosquito releases anti-coagulants when piercing skin
- #24 They are skin parasites of dogs and cats, feeding only on the blood of their hosts. great potential to act as carriers of a number of diseases
- #25 An organism obtain its food by directly using another animal or a kind of plant
- #27 Tigers / Lions and Water Buffallo
- #28 A population-based relationship wherein crowded population of organisms compete for food, space, light and other abiotic factors that are mutually needed for survival.
- #30 Manifested by a group of organisms (usually of the same species), which is beneficial to them by voiding the attackers.
- #32 A food chain starts from a trophic species that eats no other species in the web and ends at a trophic species that is eaten by no other species in the web.
- #37 sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition.
- #39 A food web (or food cycle) depicts feeding connections (who eats whom) in an ecological community.
- #43 Energy lost from one trophic level (energy level) to the next level can be represented by a pyramid
