Some apply it to the leaflets of a pinna, especially the leaflets of bipinnate or tripinnate leaves. [7] Others also or alternatively apply it to second or third order divisions of a bipinnate or tripinnate leaf. [8] It is the ultimate free division (or leaflet) of a compound leaf, or a pinnate subdivision of a multipinnate leaf.
Cyanothamnus bipinnatus is an erect shrub that grows to a height of about 1 m (3.3 ft) with pimply, glandular stems and bipinnate or tripinnate leaves. The leaves are mostly 21–50 mm (0.83–2.0 in) long and 20–60 mm (0.79–2.4 in) wide in outline with between seven and eleven leaflets, on a petiole 4–15 mm (0.16–0.59 in) long.
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Cyanothamnus inflexus is an erect, woody shrub that grows to a height of about 2 m (7 ft) and a width of about 3 m (10 ft). The leaves are pinnate, 6–25 mm (0.2–1 in) long and 6–35 mm (0.2–1 in) wide in outline on a petiole 3–10 mm (0.1–0.4 in) long.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1]
This is an incomplete list of plants with trifoliate leaves. Trifoliate leaves (also known as trifoliolate or ternate leaves) are a leaf shape characterized by a leaf divided into three leaflets. Species which are known to be trifoliate are listed here.
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.
