Epiphytes provide a rich and diverse habitat for other organisms including animals, fungi, bacteria, and myxomycetes. [5] Epiphyte is one of the subdivisions of the Raunkiær system. The term epiphytic derives from Greek epi- 'upon' and phyton 'plant'. Epiphytic plants are sometimes called "air plants" because they do not root in soil.
The largest living land animal, the African bush elephant, is a herbivore. This is a list of herbivorous animals, organized in a roughly taxonomic manner. In general, entries consist of animal species known with good certainty to be overwhelmingly herbivorous, as well as genera and families which contain a preponderance of such species.
Her theory is that, because the animals only eat the leaves of the rainforest trees they inhabit, which are always fairly toxic, the drier-than-normal weather over recent years could have caused the toxins in the leaves to become more concentrated. [9] No toxin has been identified and this hypothesis remains speculative and unsubstantiated.
Plant-animal interactions are important pathways for the transfer of energy within ecosystems, where both advantageous and unfavorable interactions support ecosystem health. [ 1 ] [ 2 ] Plant-animal interactions can take on important ecological functions and manifest in a variety of combinations of favorable and unfavorable associations, for ...
A liana is a long-stemmed woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. [1] The word liana does not refer to a taxonomic grouping, but rather a habit of plant growth – much like tree or shrub .
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome . All parasitic plants develop a specialized organ called the haustorium , which penetrates the host plant, connecting them to the host vasculature – either ...
The impact of human activity on the tundra ecosystems where pikas live has been recorded dating back to the 1970s. [18] Rather than hibernate during winter, pikas forage for grasses and other forms of plant matter and stash these findings in protected dens in a process called "haying". They eat the dried plants during the winter. [19]
Kleiber's law describes the relationship between an animal's size and its feeding strategy, saying that larger animals need to eat less food per unit weight than smaller animals. [26] Kleiber's law states that the metabolic rate (q 0 ) of an animal is the mass of the animal (M) raised to the 3/4 power: q 0 =M 3/4
