Answer: food chains or webs
In an ecosystem, energy from the sun is transferred by the way of food chains or webs. A food chain is a linear sequence of organisms through which food and energy is passed as one organism eats the another. A food web is the interconnection or relation of food chains. In a food chain energy is distributed among the trophic levels. Plants are primary producers which traps energy from sun for photosynthesis and belong to first trophic level in the food chain. The energy of sun present in plants is transferred to subsequent higher trophic levels when plants are consumed by other organisms.
answer: Neuro filaments
explanation:
Neurofilaments (NF) are intermediate filaments found in the cytoplasm of neurons. Together with microtubules and microfilaments, they form the neuronalcytoskeleton. They are believed to function primarily to provide structural support for axons and to regulate axon diameter, which influences nerve conduction velocity.
Answer:
- Society: the use of genetic improving techniques may have a positive impact through crop improvement of traits of agronomic importance such as, for example, resistance to biotic and abiotic stresses.
- Environment: the development of genetically modified crops conferring resistance to pesticides may have a negative effect on wildlife species (both plants and animals) and humans living in such agroecosystems.
Explanation:
In crops, genetic improvement technologies can be defined as the techniques associated with the development of better crop varieties, i.e., varieties that have higher grain yield, produce more biofuel, higher fiber content, etc. Genetic improvement techniques include, among others, selective breeding and genetically modified organisms. In crops, genetic improvement techniques have the potential to reduce hunger in the world. However, it is important to note that genetic engineering may be associated with the horizontal transference of genes and the development of genetically modified organisms (GMO), which may have harmful effects on wildlife species and humans, thereby GMO crops must be carefully assessed before their release into the field.
