Hi there,
How is the earthworm adapted to its feeding habits?
Well a earthworms are tube shaped, some worms such as segmented worms can be found in soil.They are there to stay moist and to feed on organic matter.
So an earthworm's<span> digestive tract is laid out straight from the oral orifice to the anus. The parts of the digestive tract regulate or absorb the nutrients from every meal.
</span>Hope this helps!
I used to have a worm farm myself, it was really cool to see really up close on how worms live and how they feed on organic matter in the soil.
Answer:
must happen before secondary succession
Can u explain more of what im supposed to be answering ?
Buffers maintain a pretty stable pH level, resisting any large changes. When introduced to a base, it will act as an acid to counteract it, and vice versa.
The sequence of impulse through the cardiac conduction system starts from SA node passes to AV node to atrioventricular bundle fibers and finally to Purkinje fibers.
Heart is an organ that receives oxygenated blood form lungs and deoxygenated blood from different parts of body. Oxygenated blood is transported to different organs and deoxygenated blood is transported to lungs for oxygenation.
Now, to perform this transportation, the auricles and ventricles of heart contract and relax. In order to contract and relax, impulse generation is required, which begins at SA node or Sinoatrial node. It is also referred to as pacemaker of the heart. SA node contracts the atria and the impulse transfers to AV node or Atrioventricular node.
This is followed by transfer of impulse to atrioventricular bundle fibers which further passes it on to Purkinje fibres for ventricular contraction. Now the blood is sent to lungs and aorta as per it's oxygen status.
