How do organisms obtain the materials and energy to carry out functions required for life?
Living organisms must take in
energy via food, nutrients, or sunlight
in order to carry out cellular processes. The transport, synthesis, and breakdown of nutrients and molecules in a cell require the use of energy.
Is chlorophyll involved in photosynthesis?
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a
green pigment
called chlorophyll. … Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.
Which of the following statements about autotrophs is incorrect?
by Biology experts to help you in doubts & scoring excellent marks in Class 10 exams. It is incorrect as ,
autotrophs can convert carbon dioxide and water into carbohydrates only in the presence of sunlight
. The autotrophs contain the green pigment clled chlorophyll which is capable of trapping sun energy.
What are the two ways by which organisms obtain their food?
- Producers (autotrophs)—self eating.
- Consumers (heterotrophs)—eat other animals.
- Decomposers –eat dead and decaying matter.
How do organisms obtain and utilize energy?
Organisms obtain
energy from the food they consume
. The food consumed by the organisms undergo cellular respiration as a result of which energy is released. Mitochondria are called power houses of the cells.
What is an organism’s niche quizlet?
A niche
describes how an organism fits into the environment
. A niche refers to where an organism lives and what it does there. … A niche includes all abiotic and biotic conditions required for the organism to survive, reproduce and maintain a viable population. You just studied 7 terms!
What best describes an organism’s habitat?
A habitat is
a place where an organism makes its home
. A habitat meets all the environmental conditions an organism needs to survive.
Which best describes habitat and niche?
A niche is
specific to a species and only supports a single species of organisms
. Habitat is a physical space occupied by species. Niche is the activities and interactions a species has with other species and the environments. Habitat represents the address of an organism.

Genetic engineering is accomplished in three basic steps. These are (1)
The isolation of DNA fragments from a donor organism
; (2) The insertion of an isolated donor DNA fragment into a vector genome and (3) The growth of a recombinant vector in an appropriate host.

Why do aquatic plants measure photosynthesis?
This experiment could certainly be done with land plants, but using a water plant makes it easier to have a simple way to measure the rate of photosynthesis–the
counting of bubbles
which come off a specific area of the plant. … They use the energy of the sun to use carbon dioxide and water to produce sugars and oxygen.
What is the source energy needed for photosynthesis so that marine plants can make their own food?
Energy from the Sun
fuels life on Earth
Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.
How do aquatic plants perform photosynthesis?
Just like plants on land, algae photosynthesize — essentially using
the sun’s rays to turn molecules of carbon dioxide and water into sugar and oxygen gas
. Underwater, those teeny tiny oxygen bubbles rush upward. As these bubbles detach from the plant, they make a short “ping” sound, the researchers found.
