Starter: (back of book)

Why does a polar bear have a smaller surface area to volume ratio than a camel?

What is mimicry?

Name 3 ways in which cacti are adapted for the arid environment in which they grow

What is

competition

?

What do

animals & plants

compete for?Slide2

Competition in

animals

What is competition?

What do animals and plants compete for?

What is the difference between

interspecific

and

intraspecific

competition?

Why can animals which rely on a single type of food be killed off so easily?

 Slide3

What is competition? Write a definition on your post-it and stick it on the large whiteboardTry and write as detailed definition as possible!Slide4

Why do animals and plants compete?

Competition: Animals and plants have to compete for limited resources. The best adapted

animals or plants will win and survive. Slide5

What are the animals competing for in each picture?

What happens if they lose?

Move area, Adopt new strategies, Extinct/dieSlide6

CompetitionAdaptations will also allow organisms to compete with other organisms for the same habitats and resources

Only those that compete successfully will be able to survive2 types of competitionInterspecific-Between individuals of different species

Intraspecific-Between individuals of the same species (only the best genes are passed on to the next generation)Slide7

Herbivores that eat a wide range of plants are likely to be more successful than picky eaters-why?If

anything happens to their food source, they will just eat something else for a whileSlide8

Clip 1: Predators & prey

ResourceHow are the predators and prey competing?What adaptations do they have to help

them?

Clip 2: How does the mimic octopus avoid predators?Clip 3: How does

(James G!) the bird attract mates? Slide9

Clip 1:

ResourceHow are the predators and prey competing?What adaptations do they have to help them?

FoodWolf-to get foodCaribou-competing not to get eaten

Run fast, good sense of smell, sharp teeth, good sight and hearing,Long legs to run fast, eyes on side of head to see predatorsSlide11

Clip 2: Avoiding predatorsThe mimic octopus makes itself look like more dangerous animals to stop itself from being attacked and eaten.

Clip 3: Attracting matesSings. Males with the most complicated songs will attract more femalesBuilds a bower and collects brightly coloured objects to decorate it. Females mate with males that have the most decorated bower.Slide12

How do animals and plants compete?

Slide13

Plants shed seeds far away so the parent plant is not in competition with its offspringTo keep tissues rigid and supported and for photosynthesisSo plants can make all the chemicals they need in their cells

For photosynthesis. Making food using the energy from the sunWhat do plants compete for?

WaterLight

Minerals & nutrients from the soilSpace

Write the subtitle in your book and match the words to the definitions. Write in full!Slide14

What are these plants competing for?

A

B

C

Write a sentence for each plant in your bookSlide15

Why do snowdrops bloom so early?

Found in woodlands with lots of tall treesWhen these trees have leaves, they block out much of the lightSmall plants e.g. snowdrop, bluebell flower early in the year when trees still have no leaves

The dormant trees take very little water out of the soil so lots available for small plantsThe plants flower, set seeds and die before the trees are in full leafSlide16

Write a subtitle: Early flowering plants in your book & underline with rulerCopy and complete the paragraph below:

Some woodland flowers e.g. ………………. and …………….. compete for water and …………. successfully. They flower early in the year whilst there are no ………… on the trees in order to get enough light for ………………… The dormant trees take very little ………..

from the soil so they compete for this successfully too.Slide17
