would you most likely see return to the ecosystem first?
A small grasses and insects
B tertiary consumers like bears and eagles
Clarge hardwood trees
D secondary consumers like skunks and foxes
Answer:
A
Explanation:
i guessed ona quiz and got it right.
The organisms that would most likely to be seen return to the ecosystem first is small grasses and insects. Thus, option A is correct.
What is an ecological pyramid?An ecological pyramid of number refers to a graphical representation which is created to show the number of organisms at each tropic level in a particular ecosystem. The pyramid has the largest size at the bottom and get smaller as the pyramid goes up.
The primary producers, which are plants are the ones that are usually found at the bottom of the pyramid and they are normally more than the consumers. Consumers are divided into primary, secondary and the tertiary consumers. The tertiary consumers are usually located at the top of the pyramid and they are often the smallest in number.
Therefore, The organisms that would most likely to be seen return to the ecosystem first is small grasses and insects. Thus, option A is correct.

Briefly explain how an animal's role in the agricultural industry determines its most desirable traits as livestock
Answer:
The livestock species play very important economic and socio-cultural roles for the wellbeing of rural households, such as food supply, source of income, asset saving, source of employment, soil fertility, livelihoods, transport, agricultural traction, agricultural diversification and sustainable agricultural production. The aim of this work was to identify and characterize the different roles that livestock and livestock species play in rural communities of Timor-Leste, highlighting the importance of animal production for the wellbeing and rural development, and relate the functions performed by livestock production with economic, social and cultural attributes of the communities. The data used in this study were collected in 2011 through a questionnaire survey in three rural communities in the district of Bobonaro, namely in a mountain area, an irrigation plain and a coastal zone, and were complemented with secondary data. Livestock production in Timor-Leste is predominantly familiar being chickens, pigs, goats, cattle, horses, buffaloes and sheep the main species. Beyond the economic function, each livestock species also performs social and cultural functions.

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the following would be a valid experiment that shows the correct relationship between gas temperature and pressure?
A.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. Then they bring the bike inside to a room temperature environment for several hours to warm up and check the pressure again. They find that the tires in the colder temperature showed a low pressure and that the pressure increased after the tires were able to warm up.

They put one soda in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the soda that had been in the freezer had burst, but the one on the counter was easy to squeeze and showed some give. They determined that the cold temperature had increased the pressure of the gas in the bottle causing it to burst.

of their life flying over the ocean but never land in
the water. What does this fact suggest about the
evolution of these physical and behavioral traits?
Answer:
Evolution changes the abilities of the Frigate birds.
Explanation:
The Frigate birds have webbed feet because they live in the ocean and unable to fly due to its big weight. Before the evolution, the Frigate birds lives in the ocean due to their large body weight but with the passage of time, evolution occurs that leads to formation of flying ability in the bird so now the bird have the old characteristics of their ancestor as well as new abilities in the physical traits of the Frigate birds due to the evolution.
