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 ...

For example, in America in 2012 there were some 78 million dogs, 86 million cats, and 3.5 million rabbits. [44] [45] [46] Anthropomorphism, the attribution of human traits to non-human animals, is an important aspect of the way that humans relate to other animals such as pets.
For example, mutualistic interactions are vital for terrestrial ecosystem function as: about 80% of land plants species rely on mycorrhizal relationships with fungi to provide them with inorganic compounds and trace elements. [7] estimates of tropical rainforest plants with seed dispersal mutualisms with animals range at least from 70% to 93.5% ...
An example of a topological food web (image courtesy of USDA) [1] The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem.
An example is the koala, because it feeds only on eucalyptus leaves. Primary consumers that feed on many kinds of plants are called generalists. 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.
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. [21] 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
Birch includes animals, plants, fungi, and microbes among critical interactions with humans: [9] plants too are incredibly important determinants: for mobile hunter-gatherers, they might dictate a seasonal move; for sedentary agriculturalists, the reliability of your crop yields means the difference between survival and extinction.
