Adaptation Example: Camel & Polar Bear. This is the first of three quizzes on the topic and it looks in particular at inter-species and intra-species competition for resources such as food, water, space and a mate. There are also factors such as food and predators. This is essential so they can pass on their to their offspring. As a part of GCSE Science, students will look at interdependence and adaptation.

The abundance and distribution of organisms in an ecosystem is determined by biotic and abiotic factors. Adaptation and Inheritance Name Tutor Group Teacher Given out: Monday 7 December Hand in: Monday 14 December .

endobj There are many birds which eat insects in our gardens, and some have evolved to only eat certain types of insect to reduce competition from other . A stable community is one in which the size of the populations of all species remain relatively constant over time. stream <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Others like the blue tit and great tit compete with other members of their own species and as well as others for different insects. Likewise, the predator is part of the prey's environment, and the prey dies if it is eaten by the predator, so it evolves whatever is necessary to avoid being eaten: speed, camouflage (to hide from the predator), a good sense of smell, sight, or hearing (to detect the predator), thorns, poison (to spray when approached or bitten), etc.Some organisms rely on the presence of organisms of a different species. This may be beneficial to both species, but it does not have to be.Lichens are another example of mutualism. In deer, and many others species, these fights competing for mates can often result in serious injury or death, but benefits the population as only the strongest pass on their genes to the next generation.The territories of animals contain all of the resources and conditions they need to survive. Full lesson ready to use straight ‘out of the box’ Similar structure to my other power points following the input - activity - review phasing Plenary sections for progress checking Clear learning objectives and outcomes Modern and engaging layout Little adaptation needed.

The darker moths survived to reproduce, … Organisms living in different habitats need different adaptations. This booklet is designed to give you some extra practise on the key areas in the “adaptation and inheritance” section of the course. During the industrial revolution, the trees around cities got sooty and darker. These include factors such as light, temperature and water, and oxygen for aquatic animals. As a result the amount of grass would decrease because the increased population of rabbits would be eating it.Often very small changes to ecosystems have large consequences, which can be difficult to predict.

Year 8 Science B3 Competition and Adaptation Revision Questions moths continued to be pale. KS3 new for the Activate resource ‘Adaptation and Inheritance’ unit. competition over territory would be between lions on the grass plains of Africa whereas above were killed, the population of rabbits would increase because they are no longer prey to the foxes. Competition can be intraspecific, or between member of the same species.Competition for mates is a common form of intraspecific competition. Competition can be interspecific or depending on whether organisms from different species or the same species are competing for resources. An Historical Overview of the American West – Supporting Resource for KS3/4 History Elena Stevens Producers are plants and algae, which photosynthesise.Primary consumers are herbivores, which eat producers.Secondary consumers are carnivores, which eat primary consumers.Tertiary consumers are also carnivores. 1 0 obj Adaptations, interdependence and competition The abundance and distribution of organisms in an ecosystem is determined by biotic and abiotic factors. Because of these, competition for food can be fierce. Camel well suited for desert: slit-like nostrils, two rows of eyelashes to keep sand out; wide, flat feet to stop them sinking into sand; thick fur to keep sun off their skin Polar Bear well suited for Arctic: black skin absorbs heat well Adaptations. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.Predator and prey evolve together. ... KS3 Key Stage 3 KS3 KS4 Key Stage 4 KS4 Adobe Reader.ppt Powerpoint.ppt. 2 0 obj %���� <> The pale moths stood out and were eaten by birds. If the population of one organism rises or falls, then this can affect the rest of the ecosystem. In the example above the amount of grass, and the numbers of rabbits and foxes all remain relatively constant. Interdependence and Adaptation KS4. The fungus in turn shelters the algae from a harsh climate.A tapeworm lives inside another animal, attaching itself to the host’s gut and absorbing its food. During the industrial revolution, the trees around cities got sooty and darker.
