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.
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. Food webs describe the transfer of energy between species in an ecosystem.
A lithoautotroph is an organism that derives energy from reactions of reduced compounds of mineral (inorganic) origin. [1] Two types of lithoautotrophs are distinguished by their energy source; photolithoautotrophs derive their energy from light, while chemolithoautotrophs (chemolithotrophs or chemoautotrophs) derive their energy from chemical reactions.

Lactuca serriola and B. lactucae have a gene-for-gene relationship, [14] meaning that each resistance gene in the plant is associated with a specific gene in the pathogen, with avirulence being dominant to virulence. [12] The possible combinations of these Dm genes can provide the plant with resistance to multiple strains of Bremia lactucae. [12]
Plant-based eating is good for the planet, given that farming animals for food is known to be one of the big contributors to greenhouse gas emissions. Are there downsides to a plant-based diet?
As they are present in food consumed in human diets and in plants used in traditional medicine of several cultures, their role in human health and disease is a subject of research. [ 1 ] [ 5 ] [ 6 ] [ 7 ] : 104 Some phenols are germicidal and are used in formulating disinfectants.
Cabbage plants. Cruciferous vegetables are vegetables of the family Brassicaceae (also called Cruciferae) with many genera, species, and cultivars being raised for food production such as cauliflower, cabbage, kale, garden cress, bok choy, broccoli, Brussels sprouts, mustard plant and similar green leaf vegetables.
Endophytes of other plant taxa perform roles such as improving plant competitive fitness, conferring biotic and abiotic stress tolerance, promoting plant growth through phytohormone production or production of limiting nutrients. [28] However, some endophytic fungi in lycophytes do produce medically relevant compounds.
