Answer:
<em>b. Branch</em>

Explanation:
In a phylogenetic tree, used to show the evolutionary relationships among various biological species or other entities; their phylogeny, node is referred to as the taxonomic unit. From the node, the species branch out into the currently living population of interest, found at the tips of lines referred to as the tree's branches.
Plants and animals live in interacting, interwined communities. There is a characteristic set of species in different environments. For example, certain species of trees, shrubs, ground cover, arthropods, reptiles, mammals, birds etc. live in a temperate forest environment. A completely different set of creatures live in a marsh, or a grassland or an agroecosystem. However, the relationships between these groups can be defined by the ecological role they play, the flow of energy between them and the cycling of nutrients between them. This is a fancy way of saying "everything is connected"! And if you change one part of the system, something else changes. In an ecosystem management decision, you hope you know what those consequences of your actions are!) This is important in managing agroecosystems as well.
A scientific theory<span> is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported </span>theories<span> are not "guesses" but reliable accounts of the real world.</span>
