Secondary consumers are small/medium-sized carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers. Tertiary consumers, which are sometimes also known as apex predators, are hypercarnivorous or omnivorous animals usually at the top of food ...
Tropical rainforest ecosystems include significant areas of biodiversity, often coupled with high species endemism. [6] Rainforests are home to half of all the living animal and plant species on the planet and roughly two-thirds of all flowering plants can be found in rainforests.
The leaves and unripened berries of the plant are toxic, and are confirmed to have killed dogs and cats. [10] However, songbirds eat the fruit without ill effects. [6] Documented cases of toxicity in humans are sparse, with many secondary sources stating that children have died from consumption of the plant.
Other plants are high in oxalates (the agent that binds calcium to form kidney stones); castor beans are the source of ricin, one of the most powerful poisons in existence; and velvet beans contain 3.1-6.1% L-DOPA, which can be toxic in large quantities. [3] The list of toxic plants is long, but toxicity does not always mean a particular plant ...

The fisheries scientist Daniel Pauly sets the values of trophic levels to one in plants and detritus, two in herbivores and detritivores (primary consumers), three in secondary consumers, and so on. The definition of the trophic level, TL, for any consumer species is: [8] = + ()
Australian Tropical Rainforest Plants, also known as RFK, is an identification key giving details—including images, taxonomy, descriptions, range, habitat, and other information—of almost all species of flowering plants (i.e. trees, shrubs, vines, forbs, grasses and sedges, epiphytes, palms and pandans) found in tropical rainforests of Australia, with the exception of most orchids which ...
