What else can I help you with?
Do all organisms acquire energy directly or indirectly from sunlight?
No, not all organisms acquire energy directly from sunlight. Primary producers such as plants and some types of bacteria use sunlight to perform photosynthesis and produce their own energy. However, other organisms, such as animals and fungi, acquire energy indirectly by consuming these primary producers or other organisms in the food chain.
What is the ultimate source for energy for food chains and webs?
microorganisms
How has evolution aided organisms in meeting their need for energy?
Some of the adaptations they develop through Evolution help them acquire energy.
What a foods web?
a food web is a model representing the many interconnected food chains and pathways on which energy flows through a group of organisms.
Which process makes sunlight energy available to all organisms in an ecosystem?
Photosynthesis is the process by which sunlight energy is converted into chemical energy by plants. This energy is then transferred to other organisms in the ecosystem through food chains and webs.
How do radiolarians get energy?
Radiolarians are single-celled organisms that obtain energy through photosynthesis or by feeding on smaller organisms, such as bacteria and algae. Through these processes, radiolarians can acquire the necessary nutrients and energy to fuel their biological functions.
How is energy transferred among organisms?
Energy is transferred among organisms through food chains or food webs. Producers, such as plants, convert sunlight into energy through photosynthesis. This energy is then passed on to consumers through consumption of other organisms. Energy is lost as heat at each trophic level, resulting in less energy available for organisms at higher trophic levels.
Animals that cannot make their own food and must eat other animals or plants to get energy are called what food relationships show where organisms get their food each member on the chain feed?
Animals that cannot make their own food and must eat other animals or plants to obtain energy are known as heterotrophs. These organisms are a part of food chains, where each member feeds on the organism below it in the chain to acquire energy.
Two different ways organisms acquire energy?
plants receive energy from the sun and water and convert it using the process of photosynthesis.mammals acquire energy from activities such as eating, drinking and sleeping.by either consuming other organisms or making its own food
How do food chain differ from food webs?
food chains are a series of steps in which organisms transfer energy,and a food web links all the food chains in an ecosystem together.
What makes up the bottom level of an energy pyramid?
The bottom level of an energy pyramid is made up of producers, such as plants and algae, that convert sunlight into energy through photosynthesis. These organisms form the foundational layer of the food chain by providing energy for all other organisms in the ecosystem.
Which level of a energy pyramid has the greatest number of organisms?
The bottom level of an energy pyramid, which consists of producers like plants, typically has the greatest number of organisms. These organisms form the base of the pyramid and support all the other levels by providing energy through photosynthesis.
