Reflection+of+science+topic+-+Ecology

====Ms Nada had actually already started teaching this topic at the end of term 2. And also at the end of term 2, we had a science trail to the Macritchie Reservoir. This science trail was for us to learn and understand more about ecology from firs hand experiences. ====

====So for this topic, what we learnt are the interactions between different organism and also their surroundings, such as the food chains, different biotic and abiotic factors that affect the environment. For the food chains, the bottom of the food chain is always the producers such as plants. And then is the herbivore which is the primary consumer. Next are herbivores or carnivores which are secondary consumers. ====

====For the abiotic and biotic environments, there are many different factors that make up these two different types of environment. For abiotic factors, as the name suggest, are the factors that is not by living things. The factors include light intensity, temperature, amount of water available, oxygen content, salinity of soil or water and PH of soil or water. While for the biotic environment, it comprises all the living organisms that an organism interacts with in its habitat, for instance, the organisms’ prey and predator. All of these factors affect how well an organism can survive in the environment. ====

====I feel that this topic is very easy. This is because many parts of the topic were being taught at primary school level such as the food chains. Also, most of the parts are quite easy to understand such as how light can affect the plants or how lack of water source can affect the organisms. ====
