What are organisms that are able to manufacture organic nutrients from substances in the abiotic environment classified as?
What are organisms that are able to manufacture organic nutrients from substances in the abiotic environment classified as?
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.
Which types of organisms listed below generally make up the decomposer community within most ecosystems?
Fungi and bacteria are the key decomposers in many ecosystems; they use the chemical energy in dead matter and wastes to fuel their metabolic processes. Other decomposers are detritivores—detritus eaters or debris eaters. These are usually multicellular animals such as earthworms, crabs, slugs, or vultures.
Which of the following obtains nutrients Autotrophs?
Autotrophs: Autotrophs absorb carbon dioxide, water and inorganic nutrients such as nitrated from the abiotic (non living) environment and use them to synthesis all the carbon compounds that they need. An external energy source such as light is needed to do this.
Which statement about evolutionary pathways is most accurate?
Answer: The statement about evolutionary pathway that is most accurate is option B. ( Two organisms on the same branch of an evolutionary pathway are more closely related to each other than to those on distant branches.)
Which farming practice causes the least harm to the environment?
Answer Expert Verified. Using Natural predators to reduce insect numbers caused the least harm to the environment.
What abiotic factor could be found in a forest ecosystem?
The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks and water. But abiotic factors can be intangible, such as temperature, other types of radiation and the chemistry of soil and water.
Which is the first organism in a food chain?
Producers
Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms.
What are the three modes of nutrition in an ecosystem?
Heterotrophs obtain organic molecules from other organisms via one of three methods: Consumers ingest organic molecules from living or recently killed organisms. Detritivores ingest organic molecules found in the non-living remnants of organisms (e.g. detritus, humus)
What is a Heterotroph example?
Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.
Which two species would most likely show the greatest similarity of DNA and proteins *?
3) Species A and E have the greatest similarity in protein structure.
Which disorder could develop in the human body when the immune system attacks a usually harmless environmental substance?
Answer Expert Verified Allergies (3) because they are the only disorder listed that is a result of the environment.
Which activity would stimulate the human immune system?
The benefit of providing vaccination is that the provided pathogen acts as an antigen and triggers the proactive immune response against the pathogen which helps in eradicating the main pathogen that has invaded the body. The vaccination is used to treat the disease like chickenpox, measles, tetanus and many others.
What are organisms that are able to manufacture organic compounds?
Some unicellular organisms produce biomass from the oxidation of inorganic compounds in hydrothermal vents in the deep ocean. These organisms are called archaea and were once grouped together with bacteria in terms of the way their composition was described.
Where do nutrients move in a biogeochemical cycle?
In nature, the nutrient elements and their compounds continuously move from the nonliving environment to the living organisms, and back to the nonliving environment. This cyclic movement of minerals from their reservoirs (air, water and soil), to the living components, and back to the reservoirs is called nutrient cyclingor biogeochemical cycles.
Where are jnutrient cycles found in an ecosystem?
JNutrient cycles are the link between abiotic and biotic components of ecosystems.
What are two processes that form the basis of an ecosystem?
The two major processes that form the basis of ecosystem functioning are energy flowand nutrient cycling. In this Unit, we will look at nutrient cycling in detail. Simply put, nutrient cycling is the cycling of nutrients required by living organisms, through different parts of the biosphere. Living organisms need food to grow and to reproduce.

How are species A and B classified in biology?
Species A is a predator and species B is its prey. (4) Species A is a scavenger and species B is its decomposer. 11. Organisms that are able to manufacture organic nutrients from substances in the abiotic environment are classified as (l ) heterotrophs (2) fungi (3) predators autotrophs 12.
What are the multiple choice questions for living environment?
Living Environment Multiple choice from August 2009. Make your selections. GOOD LUCK. Upgrade and get a lot more done! 1. Organisms that are able to manufacture organic nutrients from substances in the abiotic environment are classified as 2. Which factor would have the greatest effect on the flow of energy into an ecosystem? 3.
Where is energy not available to other organisms?
Some of the energy taken in by an organism is not available to other organisms in a food web. Energy that is not available to other organisms in a food web is energy that is (1) stored in the remains of a dead animal lost to the environment as heat (3) stored in eggs produced during sexual reproduction
