  2. Trophic level - Wikipedia

    en.wikipedia.org/wiki/Trophic_level

    The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way ...

  3. Food web - Wikipedia

    en.wikipedia.org/wiki/Food_web

    In the simplest scheme, the first trophic level (level 1) is plants, then herbivores (level 2), and then carnivores (level 3). The trophic level equals one more than the chain length, which is the number of links connecting to the base. The base of the food chain (primary producers or detritivores) is set at zero.

  4. Ecological pyramid - Wikipedia

    en.wikipedia.org/wiki/Ecological_pyramid

    A pyramid of biomass shows the relationship between biomass and trophic level by quantifying the biomass present at each trophic level of an ecological community at a particular time. It is a graphical representation of biomass (total amount of living or organic matter in an ecosystem) present in unit area in different trophic levels.

  5. Nature therapy - Wikipedia

    en.wikipedia.org/wiki/Nature_therapy

    Nature therapy, sometimes referred to as ecotherapy, forest therapy, forest bathing, grounding, earthing, Shinrin-Yoku or Sami Lok, is a practice that describes a broad group of techniques or treatments using nature to improve mental or physical health.

  6. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria ...

  7. Ecology - Wikipedia

    en.wikipedia.org/wiki/Ecology

    [87] [88] Each trophic level contains unrelated species that are grouped together because they share common ecological functions, giving a macroscopic view of the system. [89] While the notion of trophic levels provides insight into energy flow and top-down control within food webs, it is troubled by the prevalence of omnivory in real ecosystems.

  9. Energy flow (ecology) - Wikipedia

    en.wikipedia.org/wiki/Energy_flow_(ecology)

    Of all the net primary productivity at the producer trophic level, in general only 10% goes to the next level, the primary consumers, then only 10% of that 10% goes on to the next trophic level, and so on up the food pyramid. [1] Ecological efficiency may be anywhere from 5% to 20% depending on how efficient or inefficient that ecosystem is.
