Ecological classification (correct answers)
Habitat = ?
Population = ?
Community = ?
Abiotic factors = ?
Biotic factors = ?
Ecosystem = ? correct answers habitat - the place where an organism lives
population - all the organisms of one species living in a habitat
community - the populations of different species living in a habitat
abiotic - non-living factors of the environment, eg. temperature
biotic - living factors of the environment e.g. food
ecosystem - the interaction of a community of living organisms (biotic) with the non-
living (abiotic) parts of their environment
Organisms ? with other species (and members of their ? ?) for the same ?.
What is interdependence?
What does the interdependence of all living things in an ecosystem mean?
What are stable communities? correct answers compete
own
species
resources
Where, in a community, each species depends on other species for things such as food,
shelter, pollination and seed dispersal.
That any major change in an ecosystem can have far-reaching effects.
Where all the species and environmental factors are in balance so that the population
sizes are roughly constant.
Name 7 abiotic factors.
What can these factors affect? correct answers - moisture level
- light intensity
- temperature
- carbon dioxide levels (for plants)
- wind intensity and direction
- oxygen levels (for aquatic animals)
- Soil pH and mineral content
The size of the populations in a community, which means that they can also affect the
the population sizes of other organisms that depend on them.
Name 4 biotic factors.
What can these factors affect? correct answers - new predators arriving
, - competition (one species may outcompete another so that numbers are too low to
breed)
- new pathogens
- availability of food
Can affect the size of populations in a community, which can have knock-on effects
because of interdependence.
Name three types of adaptations. correct answers - structural
- behavioural
- functional
What are structural adaptations?
What are behavioural adaptations?
What are functional adaptations?
As microorganisms have a wide variety of adaptations, what can they do?
What are microorganisms that can live in extreme conditions called?
Name three conditions extremophiles can live. correct answers Features of an
organism's body structure e.g. shape or colour.
Ways that organisms behave e.g. some birds migrate at winter to warmer regions.
The things that go on inside an organism's body that can be related to processes like
reproduction and metabolism.
They can live in a wide range of environments.
Extremophiles.
- high temperatures
- places with high salt concentrations
- high pressures
What do food chains show?
What do food chains always start with?
What do they do?
When a green plant produces glucose, what is some of it used to make?
What are these biological molecules?
What is biomass? correct answers What's eaten what in an ecosystem.
A producer.
They make their own food using energy from the Sun.
Other biological molecules.
The plant's biomass.
The mass of living materials.
How is energy transferred through living organisms in an ecosystem?
What are producers eaten by?
What are primary consumers eaten by?
