What do scientists know about fossils found in deeper layers of rock compared to

Biology
1 answer:
shusha [124]4 years ago
7 0

Answer:

They know that layering, or bedding, is the most obvious feature of sedimentary rocks.  This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air. That is kinda easy :D

Does the temperature increase or decrease with altitude in the stratosphere? What
Amiraneli [1.4K]

Answer:

In this region the temperature increases with height. Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere.

What substance, produced during photosynthesis,
cricket20 [7]

Answer:

Glucose is the substance produced during photosynthesis which provides food for plants and animals in a food web.

Explanation:

The main source of energy in a food chain or food web is made by the producers. These producers are mostly plants that make food by the process of photosynthesis. As a result of photosynthesis, glucose is made as the main product whereas oxygen is made as the by-product. Glucose made is used to drive energy for all the activities of the cell. This energy, released from glucose,  is carried within an ecosystem from one organism to another.

What are two abiotic and two biotic conditions in a coral reef that provide the conditions necessary for it to have high biodive
Elena L [17]

Answer:

The two abiotic conditions in the coral reef that contribute to the high biodiversity are:

  1. Temperature
  2. Sunlight

Whilst the abiotic factors are

  1. Plant and
  2. Bacteria

Explanation:

The coral reef which covers a space of 115,831 square miles (or 30 million hectares os space) is home to a rich diversity of aquatic life (plants and animals alike). Being the largest coral reef on earth a lot of attention is given to it to ensure that its health and functionality is preserved.

The above factors contribute immensely to the stability and operability of the great reef.

The coral reef abounds with many aquatic animals such as crabs, herbivorous fish, sea turtles, sea urchins etc Many of these feed off microscopic plants such as the phytoplankton (that is tiny plants) and microscopic animals referred to as zooplankton. The zooplankton in turn feed off microscopic plant, bacterioplankton and even other zooplankton.

It is easy to see that at the base of the food chain lies Phytoplankton and bacterioplankton. This group require sunlight to thrive.

The smaller herbivorous fish, crabs, sea turtles and urchins on the other hand, constitute food for larger animals such as sharks, Baracuda etc.

It is also important to note that these microscopic life (plant and animals) require a certain temperature to thrive. If the water body in these eco system were to exceed a certain temperature, it is highly doubtful that they would survive. The death the the plant and animal life at the base of the food chain will completely disrupt the entire biodiversity and may even lead to its extinction.

Cheers!
