Human, cat, whale and bat have similar forelimb bone structure with a different functions. These homologous structures show
Answer:
The correct answer is - that They share a common ancestor.
Explanation:
The bones of forelimbs of whale, bat, cat, and human are similar in structure due to the fact they are homologous organs. Such organs which have the same basic structure but play a different role in their respective bodies are called homologous organs.
These organs are developed from the same organization during their development but due to evolutionary change in their environmental condition and their requirement, these organs are modified to perform different functions. The homologous structures are end result of divergent evolution which means they show common ancestry.

what would happen if matter could not cycle through ecosystems?
Answer: Hope This Helps!
Explanation:
When humans and animals die. How is phosphorus returned to the soil? Living things could die if the matter could not cycle through ecosystems.
Additional Information: The phosphates in plants and animals are returned to the water when the plants and animals die and decompose. Also, large amounts of phosphorus in the form of phosphates are carried by rivers and streams as runoff to the ocean.
In ecosystem, without the right nutrients in the right amounts, you can't live. Other animals and plants also need the right nutrients to live.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
An ecosystem is a community of living organisms (plants, animals and microbes) in a particular area. The term `eco' refers to a part of the world and `system' refers to the co-ordinating units.
