Ecosystems Flashcards
anther
The male part of a flower that produces pollen.
bioaccumulation
The build-up of toxic chemicals inside organisms in a food chain.
carpel
The female part of the flower, made up of the stigma where the pollen lands, style, and ovary.
community
The collection of the different types of organism present in an ecosystem.
competition
Competing with other organisms for resources.

food chain
Part of a food web, starting with a producer and ending with a top predator. This diagram shows the transfer of energy between organisms.
food web
A diagram that shows how food chains in an ecosystem are linked.
fruit
Structure that the ovary becomes after fertilisation, which contains seeds.
germination

habitat
The area in which an organism lives.
interdependence
The way in which living organisms depend on each other to survive, grow, and reproduce.
niche

ovary
The part of a flower that contains ovules.
ovule
Female sex cells in plants found in the ovary.
petal
A brightly coloured part of a flower that attracts insects.
pollen
Contains the plant male sex cells found on the stamens.
pollination
Transfer of pollen from the male part of the flower to the female part of the flower on the same or another plant.
population
Group of the same species living in an area.
predator
An animal that eats other animals.
prey
An animal that is eaten by another animal.
producer
Green plant or algae that makes its own food using sunlight by the process of photosynthesis.
seed
Structure that contains the embryo of a new plant.
seed dispersal
The movement of seeds away from the parent plant.
sepal
The special leaves found under the flower, which protect unopened buds.
stamen
The male reproductive parts of the flower.
stigma
The female part of a flower that is sticky to catch grains of pollen.
style
