Why is a food web a more realistic way of portraying an ecosystem than a food chain?

Hi. Great question. A food web is more realistic as an ecosystem's stability is a product of it's biodiversity. The more biodiverse an ecosystem is the more stable it is. I'm this sense highly stable ecosystems are highly interdependent i.e. More species will rely on each other for food. The more feeding relationship there are the more realistic it is to represent the ecosystem as a diverse, interdependent food web.

Theo Rich

ProOnline lessons

Enthusiastic and friendly tutor in Biology, Chemistry, Maths, Chinese, and 11+ / ISEB exams.

Hi there! My name is Theo and I am a Year 13 student studying Biology, Chemistry, Maths, and Chinese (4 A*s, 11 GCSE Grade 9s), looking to pursue medicine at university. I am particularly fascinated by human biology and biochemistry, but enjoy learning about other subjects that interest me, such as politics and Chinese history and culture. I thoroughly enjoy teaching, and would love to take the opportunity to share my academic knowledge and other insights as a mentor. For the last year I have worked for two hours a week as a voluntary tutor, where I have developed the skills and understanding required to be a successful tutor. I also find it incredibly exciting and rewarding to see students develop and get to grips with new topics, as well as be enthusiastic about topics I'm also keen on! I enjoy a student-led approach to tutoring, where the goals and targets of the student are our primary focus, such as an upcoming exam. What I quite like to do is, if there is a particular topic that the student would like to focus on, then we can go through the theory of it together, but if not, it can be really beneficial to go through past paper questions together and then pause and reflect on any topics that are particularly challenging.
