 * B. Answer 10 questions. **
 * 1) Define producer. Give 3 examples. Primary producers are the organisms in an ecosystem that produce biomass from inorganic compounds (autotrophs). In almost all cases these are photosynthetically active organisms (plants, cyanobacteria and a number of other unicellular organisms; see article on photosynthesis). However, there are examples of archea (unicellular organisms) that produce biomass from the oxidation of inorganic chemical compounds (chemoautotrophs) in hydrothermal vents in the deep ocean.
 * 2) Define consumer. Give 3 examples. Consumers are typically viewed as predatory animals such as the wolf and hyena. However, herbivorous animals and parasitic fungi are also consumers. Some carnivorous plants, like the v [|enus flytrap], are classified as both.
 * 3) Define herbivore. Give 3 examples. A ** herbivore ** is an [|animal] anatomically and physiologically adapted to eating plant material, for example [|foliage], for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. [|Horses] and other herbivores have wide flat teeth that are adapted to grinding [|grass] , [|tree bark] , and other tough plant material.
 * 4) Define carnivore. Give 3 examples. A ** carnivore ** is an [|organism] that derives its energy and nutrient requirements from a [|diet] consisting mainly or exclusively of [|animal] [|tissue], whether through [|predation] or [|scavenging] . Animals that depend solely on animal flesh for their nutrient requirements are considered [|obligate] carnivores while those that also consume non-animal food are considered [|facultative] carnivores. [|[2]] [|Omnivores] also consume both animal and non-animal food, and apart from the more general definition, there is no clearly defined ratio of plant to animal material that would distinguish a facultative carnivore from an omnivore. A carnivore that sits at the top of the [|food chain] is an [|apex predator].
 * 5) Define omnivore. Give 3 examples. An **omnivore** is an animal that can derive its energy and nutrients from a diet consisting of a variety of food sources that may include [|plants], [|animals] , [|algae] , [|fungi] and [|bacteria].
 * 1) Define decomposer. Give 3 examples. ** Decomposers ** or ** saprotrophs ** are organisms that break down dead or decaying organisms, and in doing so carry out the natural process of [|decomposition] . Like [|herbivores] and [|predators], decomposers are [|heterotrophic] , meaning that they use [|organic substrates] to get their [|energy] , [|carbon] and [|nutrients] for growth and development. Decomposers can break down cells of other organisms using biochemical reactions that convert the prey tissue into metabolically useful chemical products, without need for internal digestion. Decomposers use dead organisms and non-living organic compounds as their food source.
 * 2) Define scavenger. Give 3 examples. ** Scavenging ** is both a [|carnivorous] and a [|herbivorous] [|feeding behavior] in which the scavenger feeds on dead animal and plant material present in its habitat. The eating of carrion from the same species is referred to as [|cannibalism] . Scavengers play an important role in the [|ecosystem] by consuming the dead animal and plant material. [|Decomposers] and [|detritivores] complete this process, by consuming the remains left by scavengers.
 * 3) Define parasitism. Give 2 examples. ** Parasitism ** is a non-mutual [|symbiotic] relationship between [|species], where one species, the ** parasite ** , benefits at the expense of the other, the [|host] . Traditionally // parasite // referred primarily to organisms visible to the naked eye.
 * 4) Define commensalism. Give 2 examples. In [|ecology], ** commensalism ** is a class of relationships between two organisms where one organism benefits without affecting the other's parts. It can be compared with [|mutualism] , in which both organisms benefit, [|amensalism] , where one is harmed while the other is unaffected, and [|parasitism] , where one benefits while the other is harmed.
 * 5) Define mutualism. Give 2 examples. ** Mutualism ** is the way two organisms of different species exist in a relationship in which each individual benefits from the activity of the other. Similar interactions within a species are known as [|co-operation].
