biology paper 2 - b16

?
what is an eco system
the interaction of a community of non living (abiotic) parts on their environment
1 of 7
what are plants/animals often interdependent about
plants produce food by photosynthesis, animals eat plants and animals pollinate plants, animals eat other animals, use materials to build shelters, plants need nutrients from droppings and decay
2 of 7
what is interdependence
when species in a community depends on other species for food, shelter, pollination, seed dispersal. if one is removed it can affect all the community
3 of 7
what is a stable community
where all the species and environmental factors are in balance so poulation sizes remains constant
4 of 7
what are abiotic factors
non living factors that affect living organisms and communities
5 of 7
what are some examples of abiotic factors
light intensity, tempurature, moisture levels, soil ph, wind intensity, availability of oxygen and carbon dioxide
6 of 7
how can the abiotic factors affect the communities
light intensity- limits photosynthesis, the distribution of plants, some are adapted (more chlorophyll/bigger leaves) tempurature
