adaptations, interdependance and competition Flashcards
State the levels of organisation in n ecosystem
individual,population, community, ecosystem
What is an ecosystem
the interaction between the living components and the non-living components
State the factors that plants may compete for
.Light
.Space
.Water
.Mineral ions from soil
State the factors that animals may compete for
.Food
.mates
.territory
What is instraspecific competition
competition within a species
what is interspecific competition
Competition between different species
What is interdependance
Different species in an ecosystem depend on eachother, for various resources, if one species is removed the whole community may be affected
What is a stable community
A community in which all abiotic and biotic factors are balanced
What are abiotic factors
non-living factors
State the abiotic factors that may affect an ecosystem
.Light intensity
.temperature
.moisture
.Soil Ph
. Oxygen level
.Carbon dioxide level
Why might light intensity affect an ecosystem
Different species of plants may have different optimum light intensities for growth
Why does temperature affect an ecosystem
Different species may have different optimum temperatures for growth
How does soil Ph affect an ecosystem
Soil Ph may affect the appearance of the plant
How does moisture level affect an ecosystem
Many plants cannot survive in waterlogged soils as their roots cannot respire
How does wind intensity affect an ecosystem
Plant seeds are most likely to germinate in locations with lower wind intensity
How does soil mineral content affect and ecosystem
Most plants require an high amount of soil minerals to grow well
Give an example of type of plants that have adapted to low soil mineral contentin
carnivorous plants
How does carbon dioxide concentration affect an ecosystem
Higher carbon dioxide concentration leads to more plant growth
How does oxygen concentration affect an ecosystem
Some animals cannot survive in areas with low oxygen concentration
State the biotic factors that may affect an ecosystem
.Food
.New pathogens
.New predators
.Competition
What are adaptations
Features that enable organisms to survive in their living environment
What are organisms living in extreme environments called
Extermophiles
Give 3 examples of extreme living environments
.High temperature
.High pressure
.High salt concentration
State an example of where extermophile bacteria can be found
In deep sea vents
