Use quadrats to estimate the size of a population in an ecosystem Collect, analyse and present data to describe the distribution of species whose abundance has been estimated Consider the accuracy of population estimation strategies Identify factors determining the distribution of species whose abundance has been estimated Examine trends in population estimates for some plant and animal species in each environment Examine trends in population estimates for some plant and animal species within an ecosystem Justify the use of different sampling techniques to make population estimates when total counts cannot be performed Identify some adaptations of living things to factors in their environment Identify and describe in detail adaptation of a plant and an animal from the local ecosystem Analyse trends in a plant population using a transect Identify examples of allelopathy, parasitism, mutualism, and commensalism in an ecosystem and the role of organisms in each type of relationship Identify the impact of humans on the ecosystems studied {draw:frame} {draw:frame} {draw:frame}

This allows the organism to be able to hide from predators more easily in places such as under leaves or branches, and hence making it harder to see. Human impacts *o*n the mangrove Long term effects of Pollution: _ {draw:frame} _ The altered behavior of nocturnal organisms due to light pollution. E.g. Birds who use the moon and stars for navigation will be disrupted and misled if too much light is present. Excessive unnatural light may also affect some predator-prey relationships and the competitive interactions of the animals. {draw:frame} If there is excessive noise pollution, animals within the network which depend on hearing to locate their prey may have extreme difficulties. Because of this, the organism will struggle to locate its food source, or companion, causing a lower chance of survival. Also, excessive and ongoing noise pollution will cause communication issues between a certain species, therefore disrupting their natural breeding patterns. If noise is not maintained, it may cause some offspring to not be produced i.e. decreasing reproduction rates which may eventually cause the extinction of species within the
