How is the flow of energy within food webs interconnected with the cycling of<br> matter?
SVEN [57.7K]

Answer:

Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat.

Answer:

1) IV: The quantity of salt added

DV: The resultant density of the salinated water

Hypothesis: The egg will float when the  mass of the volume of the salinated solution displaced by the egg is equal to or larger than the mass of the egg

2) IV: The extension of the rubber band above original length in centimetres

DV: The distance flown by the rubber band

Hypothesis: The potential energy stored in the rubber band by pulling will be transformed into kinetic energy and the larger the extension, the larger the stored potential energy, and the larger the resultant kinetic energy, the higher the velocity and the further the distance flown

3) IV: The wing span of a paper airplane

DV: The distance flown by the plane

Hypothesis; The glide of the airplane is a factor of the wings span increased wingspan increased glide and increased travel distance

4) IV: Presence of more light

Hypothesis: Photosynthesis, which is the conversion of carbon dioxide and water into glucose and oxygen in the presence of Sunlight is essential for plant growth and the more the presence on light is increases the higher plant will tend to grow

5) IV: Amount of vinegar in the canister

DV: The height a rocket will launch

Hypothesis: With a given amount of baking soda, in the canister a little amount of vinegar causes a delayed launch but an increased build up of carbon dioxide resulting in higher height reached than when more vinegar is used in which case the lift off will be more rapid but the power will be lesser and the height reached reduced

6: IV: Surface area of the coin

DV: The number of drops held

Hypothesis: Due to surface tension and cohesion which are properties that increase with surface area and as such a coin with a larger surface area holds more water drops

7. IV: Number of hours of study

DV: Science score

Hypothesis: A student science scores is directly related to the amount of science topics thought the student is able to respond to in a test and it is directly proportional to the amount of study the student has done  related to the science topics

Name the area on a cladogram that represents the point from which the species split from the ancestor.
Rama09 [41]

Answer: Node

Explanation:

Cladograms are a graphical representation of the evolutionary relationship between organisms. These are usually shown as branches from a central point, which represents a common ancestor. In rooted cladograms, the branches are shown relative to the time elapsed since evolving from a common ancestor joined at the node, or point of divergence.

Evolution typically occurs after accumulating mutation, and natural selection of beneficial traits that confer greater chances for survival.
