Both. You can use it as singular or plural.
In a swamp a bird and a turtle feed on the same kind of fish. This will most likely result in Competition is an relations between organisms or species in which both need a resource that is in limited pool.
<h3>What is competition in an ecosystem?</h3>
Competition will happen between organisms in an ecosystem when their niches overlay , they both try to utilize the exact resource and the resource is in lack of supply.
Fuana contend for chow, water and area to live. flora contend for light, water, minerals and root area.
So,Competition is an relations between organisms or species in which both need a resource that is in limited pool.

Answer:Osteoblasts work in teams to build bone.
Explanation:They produce new bone called "osteoid" which is made of bone collagen and other protein. ... They regulate passage of calcium into and out of the bone, and they respond to hormones by making special proteins that activate the osteoclasts. OSTEOCYTES are cells inside the bone.
Answer:
Griffith concluded that in the presence of the dead S-type pneumococcus cells, some of the living R-type cells had been transformed into virulent S cells. These cells were able to grow in the bodies of the mice, causing pneumonia and multiplying in the blood. ... The DNA alone caused bacterial transformation.
Griffith introduced heat-killed 'S'- strain bacteria Streptococcus in to a mouse along with live 'R' strain bacteria. ... Some 'transforming principle' transferred from the heat-killed 'S' strain had enabled the 'R' strain to synthesise a smooth polysaccharide coat and become virulent.
In this experiments, Griffith injected mice in the lab with live R-type of bacteria. They did not suffer from the disease. ... He thus concluded that heat-killed smooth type bacterial caused a transformation of the living rough type bacteria. This experiment suggested that DNA and not proteins are the genetic material.
That'd be the cell wall and a permanent vacuole. You could also put chloroplasts :)
