What is the name given to organisms that can make their own food for the biosphere?

Autotrophs are organisms that can make their own food for the biosphere.

This term comes from the Greek terms:
Auto- meaning "self" and Troph- meaning "feeding or growth"
So autotroph quite literally means "to feed oneself". Autotrophs, for the most part, use photosynthesis from sunlight to produce their own sugars.
Plants are the primary autotrophs on Earth!

Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t

Naddik [55]

Answer:

R = 16mm/y

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

1 km = 1000 m

1 m = 100 cm

1cm = 10mm

1 km = 1,000,000 mm

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

A directional flow of electric charge

agasfer [191]

Answer:

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

How can you expect them to concern themselves with your problems?

gregori [183]

Definitely i would expect them to concern themselves with your problems when they are so beset with their own. Beset means having a lot of trouble with something, or having to deal with a lot of something causes problems. For example in a sentence; With the amount of traffic nowadays, even a trip across town is beset with dangers.

A number of major evolutionary innovations arose in the fish lineage. Check all of the evolutionary innovations associated with

Olegator [25]

Answer:

a) Teeth arose from the rough scales of ancestral sharks.

b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.

d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.

Explanation:

The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.
