Living Places Ch 5 page 184 - 188 Note to Teachers – There are 3 videos and a drag and drop interactive in the textbook.
5.1 Living Places – page 184/5 Organisms – any living things (Plant & Animal) Habitat – all organisms have a preferred living environment eg wetlands, marine, desert, rainforest – where all of their living needs are met. These Habitat requirements include: Food Water Shelter and living space Suitable Temperature Mating partners for reproduction Respiration gases eg oxygen and carbon dioxide
Needs of Living Things (Organisms) pg 185 These needs can be broken into two main categories: Biotic factors: living factors in the environment – partners, food and competitors Abiotic factors: non-living factors in the environment – rain, gases, light, wind, temperature and soil. The number and type of organisms that can live at in one time in a given environment depend of the availability and competition over the available resources. Adaptations: evolved characteristics that help an organism to survive in its environment
Read the section on Adaptations P 185/6 then choose a different Australian plant/animal/bird/fish and list 3 environmental factors that have influenced 3 adaptations of that organism.
Adaptations p 186 Animal adaptations Plant adaptations Camouflage – hide from predators or ambush prey. Mobile – to avoid predators or catch prey. Catch and eat food Take in oxygen Reproduce Spines and thorns – protect from grazing animals. Roots to take in water Large leaves to capture light or water Absorb carbon dioxide Reproduce
Environmental Conditions pg 187 Environment: the term used to describe all the conditions that affect a plant or animal in its habitat Ecologists: scientists who study the interactions between living things and their environment Biosphere: the place where all life exists; consists of Earth and its atmosphere Ecosystem: a system formed by organisms interacting with each other and their non-living surroundings in a balanced way
Interdependent: depending on each other for survival Symbiosis: another name for interdependence Commensalism: an interaction between two organisms where one of them benefits but the other one is not affected – Clown fish and sea anemones Mutualism: an interaction between organisms where both the organisms benefit from the relationship and neither is harmed – fungus and algae (lichen) Parasitism: an interaction where one type of organism (the parasite) lives on or in another type of organism (the host); the host is usually harmed or even killed – tape worms and heart worms. Select commensalism, mutualism or parasitism, then write a short paragraph to explain a another different example of this relationship. Draw up a page sized Frayer Model in your note book of your chosen relationship and give at least 2 examples for each category.
