During extremely harsh weather conditions, the tree can amputate (remove) its own branches and reduce the leaves to minimise water loss even further, then when the conditions improve, it sends out new shoots and grows a rich leafy top again. As the interior of the leaves is transparent, the sunlight can travel through to the bottom parts of the leaves which are underground and contain the chlorophyll in order to photosynthesise. The study of ecological interactions is conducted at four levels: All ecosystems combined make up the biosphere. Therefore, some of this content is revision, but the concepts have also been extended to make it more engaging at this level. 90% of the energy is lost and only 10% is made available to the next trophic level. Ex: water, sunlight, climate 2. A group of organisms of the same species that live in the same area at a specific point in time and they can interbreed with each other.

How is it adapted to life in its habitat? Poor communities often rely on small wild animals they can trap for food, but removing too many of the smaller animals could force the carnivores (like lions, leopards and wild dogs) that eat them to turn to domestic animals like sheep or cattle for food. Hunting and bushmeat - the road to extinction, Illegal hunting (poaching) of animals and the killing of wild animals for 'bush meat' in many parts of Southern Africa is of serious concern to environmentalists and is driving some species close to extinction. If teachers have taught learners to use basic light microscopes they should encourage them to study these with the use of a microscope too.

Identify the following in this food web. This online video looks at how living things adapt to their environment. Here is a quick preview: Interspecies interactions can be broken into three main categories: competition, predation, and symbiosis. Only populations of organisms that happen to have suitable characteristics are able to survive in changing conditions within an environment. A lion is an example of a predator. All rights reserved. How is this species adapted to life in its habitat? How do you think a drought and famine in a particular area, such as in Ethiopia are linked? Share lifts and carpool. Canada. Vocabulary Words covered: ecology, ecosystem, produc, ECOLOGY: Guided Notes / Self Study UNIT BUNDLE. These organisms are called consumers. You can, Students will learn about environmental interactions by studying the difference between biotic and abiotic elements, analyzing various cycles on Earth, and determining pollution's effect on our climate and vegetation, among other expectations. Ecology is the study of how organisms interact with one another and with their physical environment. 7 Life and Living, learners studied Biodiversity and Sexual Reproduction in Angiosperms, (including sections on pollination). 3. Wildebeest migrate long distances each year which coincides with the pattern of rainfall and grass growth. List and describe the levels in between the two mentioned here. What do you think would happen to this ecosystem if all the zebra got a disease and died? Or they are often put at the side, with many arrows from all levels of the food chain as they break down all the dead organisms at every level. Clipart and elements found in this PDF are copyrighted and cannot be extracted and used outside of this file without permission or license. Some parasites cause familiar human diseases. Some types of fish could eat other types of fish, the fish can eat the seaweed, the turtles eat the seaweed, the sponges filter the water for plankton. Pre-made digital activities. We have seen that organisms from one species eat other organisms from another species. Students will love this engaging and differentiated unit that explains what ecosystems are and how they interact within their environments. During the day, it hides under bushes on the river banks, but many of its home areas have been invaded by humans or destroyed. The fleas bite the human and feed, and the human is harmed in the process. Can you see how the arrows show the direction in which you must 'read' the concept map? Abiotic Factors = The nonliving parts of an organism's environment (e.g. Do you think that people should have this type of surgery to treat life-threatening obesity? For example, there are many different theories about why the dinosaurs become extinct. The leopard is adapted to run fast over short periods in order to catch its prey. [6 marks]. What pollutes the air? Together all these ecosystems make up the Earth's biosphere. Discuss the different types of interaction that exists between species. ecosystem noun community and interactions of living and nonliving things in an area. VOCABULARY habitat ecological the interactions among species and between species and their environment. In the rest of this article, we'll take take a look at the main types of interspecies interactions seen in ecological communities. The phytoplankton in the marine ecosystem and the trees in the savanna ecosystem. Explain how you know they are herbivores. One species is eating another. the bird then catches the insects as they fly up. ecology interactions within the environment getting nerdy. Some people from local communities that live on the edge of protected reserves, sneak into the reserves and illegally kill wildlife for food. - Resources Can you see how the above food chain describes how the energy is passed along from the producer to the consumers? Herbivores get energy directly from plants, but carnivores and omnivores eat animals for energy. All articles are related, so they can easily be used as paired passages, too!Students will learn and think critically about how human act. Make sure they have used the arrows in the correct direction, and that they have three levels of consumers. Which organisms are the producers in the marine ecosystem and in the savanna ecosystem? What two other animals that are poached in southern African game reserves and why are they poached? As soon as the flies land on the surface, the plant is triggered and the catchers clamp shut, catching the fly. Record what you find. A population is a group of organisms of the same species that live in the same area at a specific point in time and they can interbreed with each other. We can classify the interactions between organisms as follows: When two species in an ecosystem need to share a valuable and often limited resource.

It focuses on the behaviors of diverse organisms in their natural environment. Communities together with the non-living things in their surroundings make up an ecosystem. Animals that don't migrate sometimes go into an inactive state called hibernation in winter. Its branches are covered in white powder to reflect heat away from plant which helps to reduce water loss. Its deep roots reach ground water easily and the small leaves prevent dehydration, while still being well exposed to light due to the umbrella shape of the tree. One category of interactions describes the different ways organisms obtain their food and energy. We can trace the path of energy through an ecosystem. Compare the amount of producers with the amount of secondary consumers. Below are some example answers, but learners may come up with many more.
