Answer:
The top blank is atmospheric CO2, the right blank is combustion (i think, I can't see the bottom), the left blank is plants use CO2, the bottom blank is organisms release CO2.
Explanation:
The correct answer for the question that is being presented above is this one: "<span>Urochordata." </span>Lancelets have all chordate characteristics and segmentation in the adult. Tunicates (Sea Squirts), Subphylum: Urochordata Gill slits are the only chordate feature retained by the adult form.
Sam is studying the interaction between porcupines, pinion pine trees, and pine bark beetles. Over the course of his study in Colorado, he observes the behaviors of 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles.
His study include 3 populations
- Population ecology is the study of the factors influencing the number and distribution of animal and plant populations.
- The study of the development, control, and interactions of animal populations is known as animal population ecology.
- A population's growth may be significantly influenced by the behavior of its constituent individuals, and the presence of predators, prey, and competitors in the community will also have significant effects.
- The population is a level of organization that lies between individuals and communities, but there is no clear distinction between the phenomena that affect these levels and those of the population.
- Here Sam studies 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles. hence 3 populations are being studied here.

Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
