Begins at the level of the producer (plant) and ends at the level of the high-degree consumer.</p> <p><strong>food web<br/> </strong>A food web is comprised by the interconnected food chains of a certain community.<br/> <strong><br/> fruit body<br/> </strong>A spore-producing fungal structure. Usually the visible &quot;mushroom&quot; of the fungus.<br/> <br/> <strong>ground layer<br/> </strong>The lowest layer of vegetation on the forest floor.

Plants grow and reproduce during the growing season.<br/> <br/> <strong>heterotrophic</strong><br/> An organism that gains its energy by eating or decomposing other organisms.<br/> <br/> <b>hibernation</b><br/> An overwintering strategy used by some mammals, in which the animal's body temperature drops just above zero degrees Celsius.<br/> <strong><br/> homeothermic<br/> </strong>An animal that is capable of regulating its body temperature.<br/> <br/> <strong>hypothesis<br/> </strong>A presumption that can be tested with scientific means. For example, the statement &quot;increased nitrogen results in more plants in a lake&quot; is a hypothesis.<br/> <strong><br/> lichen<br/> </strong>A symbiotic organism that consists of a fungal and an algal part.</p> <p><strong>metamorphosis<br/> </strong>A process through which an organism develops into an adult through various different stages.</p> <p><strong>migrating bird</strong><br/> A bird species that spends its winter in a different location from its nesting region.<br/> <br/> <strong>mixed forest<br/> </strong>A forest that consist of various tree species of relatively similar prominence.</p> <p><strong>mutation</strong><br/> A change in an individual's genome (DNA molecule).<br/> <br/> <strong>mycorrhiza</strong><br/> The symbiotic structure that forms as a combination of a fungus mycelia and a plant root.<br/> <br/> <strong>natural selection</strong><br/> A phenomenon where the fittest individuals reproduce most effectively.<br/> <strong><br/> nucleus<br/> </strong>The part of the cell that contains the cell's genome in its chromosomes. <br/> <br/> <strong>nutrient</strong><br/> A substance needed by an organism to grow. For example, nitrogen and phosphorous.</p> <p><strong>park</strong><br/> A cultivated green area in a town or a city.<br/> <strong><br/> peat<br/> </strong>A soil type common to bogs. Peat is formed as the result of the slow decomposition of plant matter in anaerobic conditions.<br/> <br/> <strong>pollination</strong><br/> The transportation of a plant's pollen to another plant's pistil via birds, insects, water, or wind.</p> <p><strong>population</strong><br/> A group of individuals of the same species that inhabits the same area.</p> <p><strong>predator-prey relationship</strong><br/> A relationship between two species where the predator species benefits at the expense of the prey species.</p> <p><strong>producer</strong><br/> A plant or bacteria that produces energy via photosynthesis.<br/> <br/> <strong>producer</strong><br/> An organism that creates chemical energy through photosynthesis.<br/> <br/> <strong>sedentary bird</strong><br/> A bird species that spends all the seasons in the same region.</p> <p><strong>seed plant</strong><br/> A plant that produces seeds.</p> <p><strong>sexual reproduction</strong><br/> Reproduction that takes place with the help of sex cells or gametes (sperm cells and egg cells).<br/> <br/> <strong>site factors<br/> </strong>The environmental conditions (heat, light, water, nutrients, soil) that influence plant growth.</p> <p><strong>soil</strong><br/> The loose ground above bedrock.</p> <p><strong>spawning<br/> </strong>The reproductive method of fish.<br/> <strong><br/> spore<br/> </strong>A reproductive cell used by fungi and spore-producing plants such as mosses and ferns.</p> <p><strong>sprig</strong><br/> A woody plant under 0,5 meters tall.<br/> <strong><br/> spruce bog<br/> </strong>A forest-like bog type where spruce is the dominant tree species.<br/> <br/> <strong>succession</strong><br/> The change in forest vegetation that occurs in stages over time. <br/> <br/> <strong>symbiosis</strong><br/> A mutually beneficial relationship between two species.<br/> <strong><br/> tundra<br/> </strong>A treeless biome of the frigid zone.<br/> <strong><br/> urban forests<br/> </strong>Forested areas located near towns and cities.</p> <p><strong>vascular tissue<br/> </strong>The cells that conduct water and nutrients between the leaves and roots of a plant. <br/> <strong><br/> wet taiga forest<br/> </strong>A spruce forest.
