B7-Ecology Flashcards
What is a habitat
I place where the organism lives
What is a population
All the organisms of one species living in a habitat
What is a community
Population of different species living in a habitat
What is an abiotic factor
Nonliving factors of the environment
What is a biotic factor
Living factors of the environment
What are examples of abiotic factors
Moisture level Light intensity Temperature Carbon dioxide level Wind intensity Oxygen level Soil pH – mineral content
What are examples of biotic factors
New predators
Competition
New pathogens
Availability of food
What do plants and animals fight for within the habitats
Animals – they fight for a light, space, water, minerals
Animals fight for space, food, water, mates
What’s intraspecific competition
Competition within one species
What’s interspecific competition
Petition between species
What adaptions do you organisms partake in
Structural
Behavioural
Functional
What are structural adaptations
Changes in the organisms body structure
E.g. colour or body shape
What are behavioural adaptations
Ways that the organism behaves e.g. migration
What are the functional adaptations
The things that go on inside the organisms body that are related to a process like reproduction and metabolism
What is the order of the food chain
Producer – primary consumer – secondary consumer – Tertiary consumer
Energy is lost through the cycle
What is biodiversity
The variety of different species of organisms on Earth, or within an Ecosystem
What are the ways pollution can occur
Via water – from sewage, fertiliser or toxic chemicals
Via air-from smoke and acidic gases
Via Land-From landfill and from toxic chemicals
How does the destruction of Pete Boggs cause pollution
Pete Boggs are created from the partial decomposition of vegetable matter
– its doors are large amount of carbon
– a lodgement of CO2 is released into the atmosphere when P is dog up for:
– compost – land
How does an increasing population affect the environment
Increase population puts pressure on the environment as we take the resources we need to survive
We need more land for farming
We produce more waste
We use more land for buildings and quarries
Why does deforestation occur
Create land for buildings, quarrying, farming and dumping waste
What problems do deforestation Course
It causes less carbon dioxide to be taken in
More carbon Dioxide in the atmosphere when the trees are burnt to clear land
There is less biodiversity
What are the effects of global warming
Rising sea levels
Changing distribution of wild animals and plant species
Less biodiversity
Changes in migration pattern
How can you maintain biodiversity
Reading programs for endangered species
Protection and Regeneration of rare habitats
Rita duction of field margins and hedgerows
Reduction of 54 stations
Recycling resources
