Land plants are evolved from green algae.
Green algae called charophytes are coolest relatives of land plants.
It is believed that land plants are the most closely related to green algae, more specifically, a group of green algae referred to as charophyceans. Not only do both land plants and green algae produce chlorophyll a and b, but other evidence suggests that there is a relationship as well.
4 key traits that appear in nearly all land plants but are absent in the charophytes.
-Diploid embryos
- The ability to photosynthesize
-Apical meristem
-Walled spores produced in sporangia.
- Multicellular haploid and diploid generations
-Multicellular gametangia

Answer:
d. Both species are kept well below their carrying capacities by predators.
Explanation:
<em>According to the competitive exclusion principle, two organisms in competition cannot co-exist in the long run.</em> One of the organisms will eventually out-compete the other and the weaker organism will eventually die off due to lack of resources or relocate to another environment.
However, when both species in competition are kept well below their carrying capacities by predators or any other environmental factor, both of them can co-exist because there will be more than enough resources due to low population.
The correct option is d.
