Food Chains & Life Cycle Flashcards
What is photosynthesis and when does it occur
When plants make their own food and only during the day
How does photosynthesis work
Plants use sunlight & carbon dioxide from the air and water From the soil to make food
What is it called that makes leaves green
Chlorophyll
Do leaves that are brown / red still have chlorophyll in them and how
Yes, it’s hidden under other colors
What does chlorophyll do other than give leaves color
It takes energy from the sun, changes carbon dioxide and water into sugar and this sugar gives the plant energy to grow
Why are plants called producers
Because they make their own food
What are the 7 life processors of an animal
Moving Reproducing Sensing Feeding Breathing Excreting Growing
What the the three groups animals are divided into
Herbivores
Carnivores
Omnivores
What are herbivores and give 4 examples
Animals which eat only plants
Eg. Cows,sheep,giraffe,snails
Name the 3 of the big five which are herbivores
Rhino, elephant & buffalo
Which is the most dangerous herbivore
Hippo
- eats up to 70 kg of grass at night
What are the smallest herbivores
Insects
What are carnivores and give 4 examples
Animals that only eat meat Lions Tigers Wolves Spiders
What are omnivores and give 4 examples
Animals and humans that eat plants & meat Humans Chickens Pigs Baboons
What 3 animals are scavengers and why
Jackals, hyenas & vultures
Because they eat leftovers and carcasses of dead animals
Are dung beetles scavengers
Yes, they eat dung
What is a food chain
It describes the feeding relationship between plants and animals - shows the order of who eats what
Remember when doing a food chain,
WORD THEN ARROW
Word then arrow
What is the meaning of development in plants and animals
It is the process of maturing into an adult
Give an example of development in plants & animlas
Plants start life as a seed and develop into an adult plant
Animals start as babies and develop into adults
What is a life cycle
It is when all things grow & reproduce
What are the two life cycle processes of growth & reproduction
- Life cycle describes the stages &
process that takes place as a plant / animal grows and develops - Life cycle describes how one generation of plan or animal gives rise to the next generation through reproduction
If a life cycle has not completed what happened
The plant or animal has died
See diagrams for life cycles
Look in pictures for diagrams of life cycles
Explain the life cycle of a dandelion 7 points
Starts as a germinating seed Seeding grows and matures Mature plant makes yellow flowers Pollinated flower makes fruit Fruit has fluffy white seeds Seeds float away in the wind Seeds find new place to grow and the cycle begins
What are the 5 stages in a life cycle
Seed Seedling Adult plant Flowering plant Fruiting plant
What are 7 processes of the life cycle
Germinating Growing Maturing Flowering Pollination Fruiting Seed dispersal
What is germinating
The process in which seeds sprout
What is pollination
The transfer of pollen to different parts of a flower
What is seed dispersal
The process of spreading seeds away from the plant
How do we know if something is a mammal
It is covered in fur, it gives birth to young and suckles the young
Name the 3 stages in the life cycle of a dog

Puppy
Young animal
Mature adult
Name the 4 processes in the life cycle of the dog
See photo
Growing
Maturing
Mating
Producing babies
What the 6 stages and processes of a frog
See photo
- Female frog lays jelly like eggs
- The dark dot in the middle of each egg developers into a tadpole
- The tadpole hatches after two weeks
- As it grows its legs grow and tail gets shorter
- It become an adult frog
- the adult frog mates in spring and the life cycle begins again

Give 5 examples of animals that lay eggs
Fish, frog, snake, lizard, bird
