To ensure pollination, the chocolate tree produces tiny buds that die and rot. Ask questions and develop a line of enquiry based on observations of the real world, alongside prior knowledge and experience. The temperature may fluctuate during the year, but in some equatorial forests the average may vary as little as a few degrees throughout the year. This connection is very important to the health of the rainforest because it helps the rainforest survive from the bottom of the forest floor to the top of the rainforest canopy. However, a large part of the harnessed energy is used up by the metabolic processes of the producers (respiration). In return, the ants will protect the caterpillars. To survive in the rain forest, it is often useful to have some help from a species with which you are not competing. A case study of a sparsely populated area Himalayan Mountains, A case study of a densely populated area Greater London. Newsroom| In addition to dispersing seeds, animals are vital to tropical rainforest reproduction through flower pollination.

Rainforest Interdependence - ROSSETT GEOGRAPHY DEPARTMENT (adsbygoogle = window.adsbygoogle || []).push({}); As in all ecosystems, the different parts are lined together and depend on each other, especially in a food web with many more plants than animals. (eg toucan), By operating at night, the nocturnal animals avoid the heat of the day. Of course, in any stable ecosystem there is neither an accumulation nor a diminution in the total amount of organic matter present, so that overall there is a balance between the gross primary productivity and the total consumption. The stable tropical rainforest environment promotes diversity by allowing plants and animals to interact all year round without needing to develop protection against cold or frost. Certain insects such as ants and termites rely on each other and work as a team to build mounds where the group will live, or hunt together to find food. How does geology affect the formation of river landforms? The various mapsupplements highlight this intricate relationship between humans and the natural environment of the Amazon rain forest, and encourage decision-making practices rooted in conservation efforts. In many cases this has favoured the positioning of flowers and fruits beneath the canopy on the trunks of trees accessible to animals unable to climb or fly, an adaptation called cauliflory. Measurements show that tropical rainforests typically have biomass values on the order of 400 to 700 metric tons per hectare, greater than most temperate forests and substantially more than other vegetation with fewer or no trees.
