Answer: A.) Heterotrophs compete for the same food source.
A food chain is a linear sequence in which food and energy is being transfered when one organism is fed the another organism in an ecosystem. A food web is a interconnection of two or more food chains. Heterotrophs are organisms which are dependent upon other organisms for the food requirement. In the given condition, the lizard and frogs are the heterotrophs which are dependent upon insects for their food requirement.
<em>Hence, heterotrophs compete for the same food source is the correct statement to describe the relationship between the lizard and the frog on the food web. </em>
Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.
<u>Answer:</u>
Organisms C and D are more closely related than
Organisms A and B
<u>Explanation:</u>
Organisms A and B are not related much as the distance between them is more than the organisms C and D so the C and D are closer than A and B. The phylogenetic tree shows the biological evolutionary relationship among various biological species. So the given tree shows the relationship as mentioned above.
It also show the physical and genetic relationship among the various biological species. The phylogeny is generally shown by using a particular phylogenetic tree. For example, the simple one below which describes the different evolutionary relationships between the great apes. The genus Pongo includes orangutans, Pan includes chimpanzees and bonobos, and Homo includes humans, while Gorilla is self-evident.
According to an article/websites, the link stated below, plankton dominates the "limnetic" zone of freshwater ecosystems, which make sense since this is the topmost layer. This is the zone that receives the most sunlight, thus the plants can photosynthesize better than those at the lower levels. Plankton will rarely be found in the lowest zone as there is little to no sunlight there. The lower in the lake/freshwater ecosystem you go, the less plankton you'll find because of their lack of ability to photosynthesize. You can refer to the website below and other books/websites like it for more in-depth information on plankton and their role in freshwater ecosystems. Hope this helps.
Here is the answer of the given question above.
Often times, non-human life in an urban ecosystem is more disturbed in a way that changes happen rapidly, such as the soil and plant cover and temperature and water availability. In this kind of ecosystem, there is no stability and sustainability. On the other hand, in an undeveloped forest ecosystem, plants play a major role and that, the lives in this kind of ecosystem is undisturbed, making it more ideal for many animals to live. Hope this answer helps.
