Who are the parents of these hybrids? A group of living organisms/ All have similar characteristics/ They can interbreed and produce fertile offspring/ different species MAY have different number of chromosomes. e.g. horse = 64, donkey = 62, Mule= 63 Hybrids are infertile because their parents are of different species. What do you think a species is?

B3 L1 Adaptations Starter Activity: Extension Task dimanche 12 mai 2019dimanche 12 mai 2019 Sunday, 12 May 2019 domingo, 12 de mayo de 2019domingo, 12 de mayo de 2019 B3 L1 Adaptations Level Objective Outcome E-D Give an example of an adaptation Complete starter. C Explain how adaptations help species compete for resources. Complete demo and answer questions on slide 7. B-A* Suggest how the interdependence of species may affect particular members of a food web. Answer questions on slide 11 &12 Habitat Species Keywords Adaptations food chain Food web Starter Activity: Match the species to the habitat What makes the species suited to live in it’s habitat? Extension Task Can you change the species in any way to make it even better suited to its environment?

Living on Earth isn’t easy… Boardworks GCSE Science: Biology Adaptation Living on Earth isn’t easy… All organisms (animals and plants) are adapted to life… even you! Some organisms also have specific adaptations. These are special features or behaviours that have evolved to make an organism particularly suited to its environment. Teacher notes See the ‘Competition’ presentation for more information on niches and other ecological terms.

How are the animals and plants adapted to their environments?

What is competition? Boardworks GCSE Science: Biology Competition All living things need natural resources, but the problem is that there is not enough for everyone. This means that living things have to fight (compete) for them in order to survive. This struggle for resources is called competition. Animals may compete for territory, food, mates, living space. Plants may compete for space, light, nutrients and water. What things might animals or plants compete with each other for? 8

Adaptations When we are older what sort of things will we be competing with each other for? Are we competing for anything now? Level Objective Outcome E-D Define species Complete starter. C Explain how adaptations help species compete for resources. Complete demo and answer questions on slide 7. B-A* Suggest how the interdependence of species may affect particular members of a food web. Answer questions on slide 11 &12 9

Food webs Answer the questions below! What might plants growing on the woodland floor compete for? If there was a decrease ↓ in heather, how would it affect: Rabbits? Shrews? Foxes? Owls
