In this first lesson on the topic of Ecology, understand a lot of the key words such as species, populations, community, ecosystem and habitat. We then look at competition in plants and animals, what is meant by the term interdependence and what makes a stable community. We then look at abiotic and biotic factors and explain how changes in these factors can have significant and far reaching changes in a community. As ever, we finish with exam practise to help you squeeze the most marks out of your next exams as possible!
