Many tropical food plants are propagated by cuttings.Seeds are necessary for plant embryos to survive the winter and other harsh conditions such as drought.However, where the weather is normally conducive to growth year-round, plants reproducing plants through means other than seeds is often advantageous.
Within an ecological food chain, consumers are categorized into primary consumers, secondary consumers, and tertiary consumers. [3] Primary consumers are herbivores, feeding on plants or algae. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).
Consumer–resource interactions are the core motif of ecological food chains or food webs, [1] and are an umbrella term for a variety of more specialized types of biological species interactions including prey-predator (see predation), host-parasite (see parasitism), plant-herbivore and victim-exploiter systems. These kinds of interactions ...
Tropical rainforests provide timber as well as animal products such as meat and hides. Rainforests also have value as tourism destinations and for the ecosystem services provided. Many foods originally came from tropical forests, and are still mostly grown on plantations in regions that were formerly primary forest. [39]

Two of the largest palm oil plantations in Peru are located on the west side of the Ucayali River, which flows from the Andes to the Amazon. From above, the surrounding landscape looks like ...
These forests offer essential resources for human survival and well-being: [44] Provision of Food: They provide a source of food through the collection of fruits, nuts, and edible plants, particularly for local communities living in or near the forest. [45] Some specific forest products include:
Trophic species are functional groups that have the same predators and prey in a food web. Common examples of an aggregated node in a food web might include parasites, microbes, decomposers, saprotrophs, consumers, or predators, each containing many species in a web that can otherwise be connected to other trophic species.
